Learn more: PostgreSQL 18 open-source release announcement Supported versions of PostgreSQL in Azure Database for PostgreSQL Analytics Real-time analytics with Fabric Mirroring (GA) With Fabric mirroring in Azure Database for PostgreSQL, now generally available, you can run your Microsoft Fabric analytical workloads and capabilities on near-real-time replicated data, without impacting the performance of your production PostgreSQL databases, and at no extra cost. Mirroring in Fabric connects your operational and analytical platforms with continuous data replication from PostgreSQL to Fabric. Transactions are mirrored to Fabric in near real-time, enabling advanced analytics, machine learning, and reporting on live data sets without waiting for traditional batch ETL processes to complete. This approach eliminates the overhead of custom integrations or data pipelines. Production PostgreSQL servers can run mission-critical transactional workloads without being affected by surges in analytical queries and reporting. With our GA announcement Fabric mirroring is ready for production workloads, with secure networking (VNET integration and Private Endpoints supported), Entra ID authentication for centralized identity management, and support for high availability enabled servers, ensuring business continuity for mirroring sessions. Learn more: Mirroring Azure Database for PostgreSQL flexible server Adding Parquet support to the azure_storage extension (GA) In addition to mirroring data directly to Microsoft Fabric, there are many other scenarios that require moving operational data into data lakes for analytics or archival. The complexity of building and maintaining ETL pipelines can be expensive and time-consuming. Azure Database for PostgreSQL now natively supports Parquet via the azure_storage extension, enabling direct SQL-based read/write to Parquet files in Azure Storage. This makes it easy to import and export data in Postgres without external tools or scripts. Parquet is a popular columnar storage format often used in big data and analytics environments (like Spark and Azure Data Lake) because of its efficient compression and query performance for large datasets. Now you can use the azure_storage extension to can skip an entire step: just issue a SQL command to write to and query from a Parquet file in Azure Blob Storage. Learn more: Azure storage extension in Azure Database for PostgreSQL Analytical queries inside PostgreSQL with the pg_duckdb extension (Preview) DuckDB’s columnar engine excels at high performance scans, aggregations and joins over large tables, making it particularly well-suited for analytical queries. The pg_duckdb extension, now available in preview for Azure Database for PostgreSQL combines PostgreSQL’s transactional performance and reliability with DuckDB’s analytical speed for large datasets. Together pg_duckdb and PostgreSQL are an ideal combination for hybrid OLTP + OLAP environments where you need to run analytical queries directly in PostgreSQL without sacrificing performance., To see the pg_duckdb extension in action check out this demo video: https://aka.ms/pg_duckdb Learn more: pg_duckdb – PostgreSQL extension for DuckDB Security Meet compliance requirements with the credcheck, anon & ip4r extensions (GA) Operating in a regulated industry such as Finance, Healthcare and Government means negotiating compliance requirements like HIPAA and PCI-DSS, GDPR that include protection for personalized data and password complexity, expiration and reuse. This week the anon extension, previously in preview, is now generally available for Azure Database for PostgreSQL adding support for dynamic and static masking, anonymized exports, randomization and many other advanced masking techniques. We’ve also added GA support for the credcheck extension, which provides credential checks for usernames, and password complexity, including during user creation, password change and user renaming. This is particularly useful if your application is not using Entra ID and needs to rely on native PostgreSQL users and passwords. If you need to store and query IP ranges for scenarios like auditing, compliance, access control lists, intrusion detection and threat intelligence, another useful extension announced this week is the ip4r extension which provides a set of data types for IPv4 and IPv6 network addresses. Learn more: PostgreSQL Anonymizer credcheck – PostgreSQL username/password checks IP4R - IPv4/v6 and IPv4/v6 range index type for PostgreSQL The Azure team maintains an active pipeline of new PostgreSQL extensions to onboard and upgrade to Azure Database for PostgreSQL For example, another important extension upgraded this week is pg_squeeze which removes unused space from a table. The updated 1.9.1 version adds important stability improvements. Learn more: List of extensions and modules by name Integrated identity with Entra token-refresh libraries for Python In a modern cloud-connected enterprise, identity becomes the most important security perimeter. Azure Database for PostgreSQL is the only managed PostgreSQL service with full Entra integration, but coding applications to take care of Entra token refresh can be complex. This week we’re announcing a new Python library to simplify Entra token refresh. The library automatically refreshes authentication tokens before they expire, eliminating manual token handling and reducing connection failures. The new python_azure_pg_auth library provides seamless Azure Entra ID authentication and supports the latest psycopg and SQLAlchemy drivers with automatic token acquisition, validation, and refresh. Built-in connection pooling is available for both synchronous and asynchronous workloads.

The growing popularity, maturity and low cost of PostgreSQL has led to a healthy demand for migration tooling to simplify these steps. The new AI-assisted Oracle Migration Tool preview announced this week greatly simplifies moving from Oracle databases to Azure Database for PostgreSQL. Available in the VS Code PostgreSQL extension the new migration tool combines GitHub Copilot, Azure OpenAI, and custom Language Model Tools to convert Oracle schema, database code and client applications into PostgreSQL-compatible formats. Unlike traditional migration tools that rely on static rules, Azure’s approach leverages Large Language Models (LLMs) and validates every change against a running Azure Database for PostgreSQL instance. This system not only translates syntax but also detects and fixes errors through iterative re-compilation, flagging any items that require human review. Application codebases like Spring Boot and other popular frameworks are refactored and converted. The system also understands context by querying the target Postgres instance for version and installed extensions. It can even invoke capabilities from other VS Code extensions to validate the converted code. The new AI-assisted workflow reduces risk, eliminates significant manual effort, and enables faster modernization while lowering costs.

We publish monthly recaps about new features in Azure Database for PostgreSQL, as well as an annual blog about what’s new in Postgres at Microsoft.Announcing Azure HorizonDB
Affan Dar, Vice President of Engineering, PostgreSQL at Microsoft Charles Feddersen, Partner Director of Program Management, PostgreSQL at Microsoft Today at Microsoft Ignite, we’re excited to unveil the preview of Azure HorizonDB, a fully managed Postgres-compatible database service designed to meet the needs of modern enterprise workloads. The cloud native architecture of Azure HorizonDB delivers highly scalable shared storage, elastic scale-out compute, and a tiered cache optimized for running cloud applications of any scale. Postgres is transforming industries worldwide and is emerging as the foundation of modern data solutions across all sectors at an unprecedented pace. For developers, it is the database of choice for building new applications with its rich set of extensions, open-source API, and expansive ecosystems of tools and libraries. At the same time, but at the opposite end of the workload spectrum, enterprises around the world are also increasingly turning to Postgres to modernize their existing applications. Azure HorizonDB is designed to support applications across the entire workload spectrum from the first line of code in a new app to the migration of large-scale, mission-critical solutions. Developers benefit from the robust Postgres ecosystem and seamless integration with Azure’s advanced AI capabilities, while enterprises can gain a secure, highly available, and performant cloud database to host their business applications.

Backups are fully automated, and integration with Azure Defender for Cloud provides additional protection for highly sensitive data. All up, Azure HorizonDB offers enterprise-grade security, compliance, and reliability, making it ready for business use today. Since the launch of ChatGPT, there has been an explosion of new AI apps being built, and Postgres has become the database of choice due in large part to its vector index support. Azure HorizonDB extends the AI capabilities of Postgres further with two key features. We are introducing advanced filtering capabilities to the DiskANN vector index which enable query predicate pushdowns directly into the vector similarity search. This provides significant performance and scalability improvements over pgvector HNSW while maintaining accuracy and is ideal for similarity search over transactional data in Postgres. The second feature is built-in AI model management that seamlessly integrates generative, embedding, and reranking models from Microsoft Foundry for developers to use in the database with zero configuration. In addition to enhanced vector indexing and simplified model management to build powerful new AI apps, we’re also pleased to announce the general availability of Microsoft’s PostgreSQL Extension for VS Code that provides the tooling for Postgres developers to maximize their productivity. Using this extension, GitHub Copilot is context aware of the Postgres database which means less prompting and higher quality answers, and in the Ignite release, we’ve added live monitoring with one-click GitHub Copilot debugging where Agent mode can launch directly from the performance monitoring dashboard to diagnose Postgres performance issues and guide users to a fix. Alpha Life Sciences are an existing Azure customers “I’m truly excited about how Azure HorizonDB empowers our AI development. Its seamless support for Vector DB, RAG, and Agentic AI allows us to build intelligent features directly on a reliable Postgres foundation. With Azure HorizonDB, I can focus on advancing AI capabilities instead of managing infrastructure complexities. It’s a smart, forward-looking solution that perfectly aligns with how we design and deliver AI-powered applications.” Pengcheng Xu, CTO Alpha Life Sciences For enterprises that are modernizing their applications to Postgres in the cloud, the security and availability of Azure HorizonDB make it an ideal platform. However, these migrations are often complex and time consuming for large legacy codebase conversions. To simplify this and reduce the risk, we’re pleased to announce the preview of GitHub Copilot powered Oracle migration built into the PostgreSQL Extension for VS Code. Built into VS Code, teams of engineers can work with GitHub Copilot to automate the end-to-end conversion of complex database code using rich code editing, version control, text authoring, and deployment in an integrated development environment.

Architecting Secure PostgreSQL on Azure: Insights from Mercedes-Benz
Authors: Johannes Schuetzner, Software Engineer at Mercedes-Benz & Nacho Alonso Portillo, Principal Program Manager at Microsoft When you think of Mercedes-Benz, you think of innovation, precision, and trust. But behind every iconic vehicle and digital experience is a relentless drive for security and operational excellence. At Mercedes-Benz R&D in Sindelfingen, Germany, Johannes Schuetzner and the team faced a challenge familiar to many PostgreSQL users: how to build a secure, scalable, and flexible database architecture in the cloud—without sacrificing agility or developer productivity. This article shares insights from Mercedes-Benz about how Azure Database for PostgreSQL can be leveraged to enhance your security posture, streamline access management, and empower teams to innovate with confidence. The Challenge: Security Without Compromise “OK, let’s stop intrusions in their tracks,” Schuetzner began his POSETTE talk, setting the tone for a deep dive into network security and access management. Many organizations need to protect sensitive data, ensure compliance, and enable secure collaboration across distributed teams. The typical priorities are clear: Encrypt data in transit and at rest Implement row-level security for granular access Integrate with Microsoft Defender for Cloud for threat protection Focus on network security and access management—where configuration can make the biggest impact Building a Secure Network: Private vs. Public Access Mercedes-Benz explored two fundamental ways to set up their network for Azure Database for PostgreSQL: private access and public access. “With private access, your PostgreSQL server is integrated in a virtual network. With public access, it is accessible by everybody on the public internet,” explained Schuetzner. Public Access: Public endpoint, resolvable via DNS Firewall rules control allowed IP ranges Vulnerable to external attacks; traffic travels over public internet Private Access: Server injected into an Azure VNET Traffic travels securely over the Azure backbone Requires delegated subnet and private DNS VNET peering enables cross-region connectivity “One big benefit of private access is that the network traffic travels over the Azure backbone, so not the public internet,” said Schuetzner. This ensures that sensitive data remain protected, even as applications scaled across regions. An Azure VNET is restricted to an Azure region though and peering them may be complex. Embracing Flexibility: The Power of Private Endpoints Last year, Azure introduced private endpoints for PostgreSQL, a significant milestone in Mercedes-Benz’s database connectivity strategy. It adds a network interface to the resource that can also be reached from other Azure regions. This provides the resources in the VNET associated with the private endpoint to connect to the Postgres server. The network traffic travels securely over the Azure backbone. Private endpoints allow Mercedes-Benz to: Dynamically enable and disable public access during migrations Flexibly provision multiple endpoints for different VNETs and regions Have explicit control over the allowed network accesses Have in-built protection from data exfiltration Automate setup with Terraform and infrastructure-as-code This flexibility can be crucial for supporting large architectures and migration scenarios, all while maintaining robust security. Passwordless Authentication: Simplicity Meets Security Managing database passwords is a pain point for every developer. Mercedes-Benz embraced Azure Entra Authentication (formerly Azure Active Directory) to enable passwordless connections. Passwordless connections do not rely on traditional passwords but are based on more secure authentication methods of Azure Entra. They require less administrational efforts and prevent security breaches. Benefits include: Uniform user management across Azure resources Group-based access control Passwordless authentication for applications and CI/CD pipelines For developers, this means less manual overhead and fewer risks of password leaks. “Once you have set it up, then Azure takes good care of all the details, you don’t have to manage your passwords anymore, also they cannot be leaked anymore accidentally because you don’t have a password,” Schuetzner emphasized. Principle of Least Privilege: Granular Authorization Mercedes-Benz appreciates the principle of least privilege, ensuring applications have only the permissions they need—nothing more. By correlating managed identities with specific roles in PostgreSQL, teams can grant only necessary Data Manipulation Language (DML) permissions (select, insert, update), while restricting Data Definition Language (DDL) operations. This approach minimizes risk and simplifies compliance. Operational Excellence: Automation and Troubleshooting Automation is key to Mercedes-Benz’s success. Using Terraform and integrated in CI/CD pipelines, the team can provision identities, configure endpoints, and manage permissions—all as code. For troubleshooting, tools like Azure Bastion enable secure, temporary access to the database for diagnostics, without exposing sensitive endpoints. The Impact: Security, Agility, and Developer Empowerment By leveraging Azure Database for PostgreSQL, Mercedes-Benz can achieve: Stronger security through private networking and passwordless authentication Flexible, scalable architecture for global operations Streamlined access management and compliance Empowered developers to focus on innovation, not infrastructure Schuetzner concluded, “Private endpoints provide a new network opportunity for Postgres on Azure. There are additional costs, but it’s more flexible and more dynamic. Azure takes good care of all the details, so you don’t have to manage your passwords anymore. It’s basically the ultimate solution for password management.” Mercedes-Benz’s story shows that with the right tools and mindset, you can build secure and scalable solutions on Azure Database for PostgreSQL. For more details, refer to the full POSETTE session.Introducing support for Graph data in Azure Database for PostgreSQL (Preview)
We are excited to announce the addition of Apache AGE extension in Azure Database for PostgreSQL, a significant advancement that provides graph processing capabilities within the PostgreSQL ecosystem. This new extension brings a powerful toolset for developers looking to leverage a graph database with the robust enterprise features of Azure Database for PostgreSQL.New ESG study validates how fully managed PostgreSQL on Azure delivers economic wins
Migrating your PostgreSQL databases to Azure delivers cost, performance and productivity benefits, while laying a strong foundation for innovation. But don’t just take our word for it. We’ve worked with the Enterprise Strategy Group (ESG), now a part of Omdia, to validate how organizations benefit economically from moving their PostgreSQL databases to Azure. Whether you’re modernizing your mission-critical applications or developing the next groundbreaking feature, migrating to Azure gives you the freedom, flexibility and continuous improvements of open source backed by the reliability, security and efficiency of Azure. Read the full PostgreSQL report PostgreSQL is the preferred choice of developers building the next generation of intelligent applications, according to the 2025 Stack Overflow survey. However, many teams are finding that managing these open-source databases on-premises is increasingly challenging, especially as their innovation initiatives demand more and more resources. Because of this, organizations are rapidly modernizing their database infrastructure to better support these next-gen initiatives. At a glance – benefits of migrating to Azure Database for PostgreSQL Increasing complexity is nothing new to today’s IT and developer teams. Some of the key drivers contributing to this complexity include integrating emerging tech like AI and managing cybersecurity concerns—two things that the fully managed Azure Database for PostgreSQL service handles very well. Built-in GenAI capabilities, performance recommendations, and enterprise-grade security, scalability, compliance and availability make PostgreSQL on Azure a natural fit for teams looking to build intelligent enterprise applications. The ESG report highlights: 58% lower total cost of ownership 65% improvement in database performance $770K in savings from avoiding downtime “We have seen wins on both sides of the financial equation. Our costs are down across the board, and we have increased our revenue specifically because of the capabilities that moving our Azure Database for PostgreSQL.” Review the Azure Database for PostgreSQL Economic Validation Infographic A closer look – how fully managed PostgreSQL on Azure delivers economic wins for the enterprise Lower total cost of ownership Migration dramatically lowers the total cost of ownership of enterprise databases. By shifting from on-premises infrastructure to Azure’s managed service, enterprises eliminate many capital and operational expenses. Elimination of hardware and maintenance costs: On-premises PostgreSQL deployments require investing in servers, storage, networking hardware, as well as ongoing power, cooling, and data center space. Migrating to Azure removes these needs entirely. Companies no longer have to purchase or refresh hardware or pay for associated facilities and utilities, directly cutting capex and support costs. Reduced licensing and support expenses: Azure’s model also eliminates traditional database licensing fees, third-party support contracts, and expensive monitoring tools for on-premises systems. Organizations reported saving thousands on separate support agreements or software licenses for their PostgreSQL instances. Pay-as-you-go flexibility: Azure Database for PostgreSQL offers pay-as-you-go and reserved pricing models, so enterprises only pay for the compute and storage they actually use. There’s no more overprovisioning resources to handle peak loads, and dynamic scaling ensures capacity matches demand. Operational efficiency: By offloading database management to Microsoft, organizations also reduce administrative overhead, which indirectly lowers labor costs. In ESG’s study, moving to Azure cut the monthly DBA hours per database from 2.1 hours to just 0.6 hours, a ~70% decrease in effort, effectively saving payroll expenditure on routine upkeep. Improved performance and scalability Enterprises see substantial improvements in database performance and scalability after migrating to Azure. Because Azure Database for PostgreSQL runs on high-end cloud infrastructure with intelligent optimizations, applications can achieve faster response times and handle greater workloads. Higher throughput and lower latency: ESG’s interviews found average database performance improved by ~65%, and in one case a customer saw a 9× increase in throughput for its primary application after migration. Such gains come from Azure’s optimized compute, premium SSD storage options, and features like automatic performance tuning that are difficult to replicate on-premises. Elastic scaling on demand: In on-premises environments, supporting peak workloads often meant overprovisioning. Azure Database for PostgreSQL completely changes this paradigm with cloud elasticity. The ability to instantly right-size resources means applications always have the performance they need, and users experience responsive, low-latency service. Handling growth with ease: As an enterprise’s data and user base grows, Azure’s global infrastructure can seamlessly accommodate that expansion. This cloud scalability gives enterprises headroom to innovate and onboard more customers without performance bottlenecks. In contrast, scaling an on-premises PostgreSQL often requires complex sharding or hardware upgrades. Accelerated time to value: Improved performance and scalability directly impact business agility. Batch processes complete faster, reports generate sooner, and websites or applications can serve more customers per second. ESG noted that by removing infrastructure constraints, Azure empowered businesses to accelerate their time-to-value and respond faster to market demands. Operational agility and developer productivity By migrating to a fully managed service, enterprises gain agility and allow their IT/development teams to focus on innovation. Offloading database management to Azure not only saves costs but also frees up technical staff from mundane maintenance. This shift translates into faster project delivery and greater productivity: Less time spent “keeping the lights on”: ESG found that after migration, companies saw a major reduction in the effort required to manage databases. Administrators went from spending 2+ hours per database per month on upkeep to less than one hour. This over 70% drop in DBA workload means IT teams are no longer bogged down by routine chores. Faster development and release cycles: ESG observed that organizations enjoyed increased development velocity after migrating, since their engineers could devote time to coding and testing new features instead of managing database infrastructure. For example, one company in the study was able to increase its software release frequency significantly. Improved business agility: The combination of easier scaling, better performance, and less ops overhead means the organization can respond to opportunities faster. Some enterprises even credited the move to Azure with helping increase their revenue, because it allowed them to deliver new capabilities to market sooner. Focus on core competencies: After migration, organizations can let Azure handle the heavy lifting of database administration and instead concentrate on work that differentiates them in the marketplace. Developers spend more time building applications and analyzing areas that drive business value rather than performing software updates or fixing replication issues. Enhanced security, compliance, and reliability Azure Database for PostgreSQL provides enterprise-grade security and reliability features that far exceed what most companies can achieve on-premises. This results in a stronger risk posture, reducing the likelihood of breaches or downtime while also easing compliance burdens. Built-in high availability and disaster recovery: ESG’s modeled scenario saw annual PostgreSQL downtime drop from 10 hours on-premises to just 5 hours on Azure. With a 99.99% availability SLA for Azure Database for PostgreSQL, unplanned outages that used to disrupt business are largely a thing of the past. One ESG case study estimated about $770K in costs were avoided thanks to preventing downtime and the associated business disruptions. Strong security and data protection: PostgreSQL instances on Azure benefit from Microsoft’s massive investments in cybersecurity and compliance. One customer highlighted, “We are much more secure since we moved to Azure Database for PostgreSQL. We use Azure AI to set our security standards and get constant recommendations on how to increase our security even more.” Automated updates and governance: Azure takes care of updating PostgreSQL with the latest security fixes and can even upgrade the database engine version with minimal downtime.
