Previously, while you could create custom casts, it wasn’t possible to drop them once they were no longer needed. With this update, you can now use the PostgreSQL DROP CAST command to clean up unused or obsolete casts, making it easier to manage schema customizations over time. Example: CREATE CAST (bigint AS text) WITH INOUT; … DROP CAST IF EXISTS (bigint AS text); Latest PostgreSQL minor versions: 18.4, 17.10, 16.14, 15.18, 14.23 Azure Database for PostgreSQL now supports the latest PostgreSQL minor versions: 18.4, 17.10, 16.14, 15.18, and 14.23. These updates are applied automatically during planned maintenance windows, helping keep your databases current with the latest PostgreSQL community fixes and reliability improvements, with no manual action required. This release includes fixes across query correctness, planner behavior, replication, backup and restore tooling, logical replication, foreign data wrapper behavior, and timezone data, improving overall stability and correctness of database operations. For details about the minor release, see the PostgreSQL announcement. Azure PostgreSQL Learning Bytes 🎓 Generate a pgBadger report from Server Logs Need a quick workload readout from PostgreSQL logs? Use pgBadger with Azure PostgreSQL Server Logs. Fast path: Server logs → Download '.log' files → Generate pgBadger report Before collecting logs, set log_line_prefix in Server parameters: %m user=%u db=%d pid=%p: Then enable Server logs > Capture logs for download, download the .log files for the time window you want to analyze, place them in a local folder, and run: FOLDER=<logs-folder-name> pgbadger -f stderr \ --prefix '%m user=%u db=%d pid=%p:' \ ./$FOLDER/*.log \ -o ./$FOLDER/pgbadger-report.html Open the generated report: start ./$FOLDER/pgbadger-report.html This gives you a quick HTML report for query activity, connection patterns, events, lock waits, and workload spikes - without setting up a storage account, BlobFuse mount, or JSON extraction pipeline. 💡Tip: Start with one or two hourly log files first. Confirm the report looks right, then expand the log analysis window. Learn more: Log Insights in Minutes: A Simpler pgBadger WorkflowLog Insights in Minutes: A Simpler pgBadger Workflow
Sometimes the fastest way to understand a PostgreSQL workload is not another dashboard. It is a good log report. pgBadger is a PostgreSQL log analysis tool that turns raw PostgreSQL logs into an interactive HTML report. It helps summarize query activity, connection patterns, errors, temporary files, lock waits, autovacuum activity, and more. Earlier guidance for generating pgBadger reports from Azure Database for PostgreSQL Flexible Server focused on exporting logs through Diagnostic Settings, storing them in a storage account, and then using tools such as BlobFuse and jq to extract PostgreSQL log lines from JSON files. That workflow is still useful when customers centralize logs across multiple servers. However, if you are already using the Server logs feature in Azure Database for PostgreSQL Flexible Server, there is a much simpler path. In this post: You’ll learn how to generate a pgBadger HTML report from Azure Database for PostgreSQL Flexible Server by downloading native PostgreSQL .log files directly from the Azure portal. No storage account, BlobFuse mount, or JSON extraction required. Fast path Configure log_line_prefix . Enable Server logs for download. Download the PostgreSQL .log files. Run pgBadger with the matching prefix. Open pgbadger-report.html . Why use this workflow? With Server logs, you can download native PostgreSQL .log files directly from the Azure portal and run pgBadger locally. Older path Simpler path in this blog Diagnostic Settings → Storage account → BlobFuse → JSON extraction → pgBadger Server logs → Download .log files → pgBadger Area Older Diagnostic Settings workflow Server logs workflow Export path Diagnostic Settings to storage account Download .log files directly from the portal Format JSON payloads need extraction Native PostgreSQL .log files Extra tooling BlobFuse and jq JSON parsing None Best suited for Centralized or multi-server logging Quick per-server analysis Outcome Flexible, but more setup Faster path to pgBadger Recommended: Use the Server logs workflow when you want a fast, low-friction way to generate a pgBadger report from one Azure Database for PostgreSQL Flexible Server. When should you use this workflow? Use this workflow when... Use Diagnostic Settings when... You need a quick report for one Flexible Server. You centralize logs from many servers. You want to run pgBadger locally. You need long-term retention or workspace-level querying. You want to avoid JSON extraction. You already have automated log export pipelines. Before you start A machine where you can install or run pgBadger. A working Perl runtime. Git Bash on Windows, so the multi-line shell commands work as shown. Portal access to your Azure Database for PostgreSQL Flexible Server. Permission to update server parameters and enable Server logs. Important: pgBadger can only analyze what PostgreSQL logs capture. To populate query timing and slow-query sections in the report, enable log_min_duration_statement before collecting logs. Logs collected before that change will not include duration data. Workflow overview Task Type Rough effort Install or prepare pgBadger One-time setup per analysis machine 5–10 minutes Configure log_line_prefix One-time setup per server 2–3 minutes Enable Server logs One-time setup per server 2–3 minutes Download logs and run pgBadger Repeatable 2–5 minutes Install or prepare pgBadger on the machine where you will analyze logs. Configure log_line_prefix so pgBadger can parse each log line. Enable Server logs, so PostgreSQL logs are available for download. Download the logs and run pgBadger locally. 💡Pro tip: Start with a narrow log window first. Use one or two hourly log files, confirm the report looks right, and then expand the analysis window if needed. Step 1: Install pgBadger Before generating a report, you need pgBadger available on the machine where you plan to analyze the downloaded PostgreSQL log files. Run this on a Linux VM, WSL, or another Linux-based environment where you can install packages. Note: Azure Cloud Shell may work for quick testing, but package installation and build-tool availability can vary by session. For repeatable analysis, use a Linux VM, WSL, or another environment you control. Copy and run sudo apt-get update && sudo apt-get install -y git perl make gcc && \ git clone https://github.com/darold/pgbadger.git && \ cd pgbadger && \ perl Makefile.PL && \ make && \ sudo make install && \ pgbadger -V What good looks like: The install command completes successfully and pgbadger -V returns the installed pgBadger version. Step 2: Configure log_line_prefix This is a one-time server configuration step. The log_line_prefix parameter controls the beginning of each PostgreSQL log line. pgBadger uses this prefix to extract useful fields such as timestamp, user, database, and process ID. In the Azure portal, open your Flexible Server and go to Server parameters. Search for: Parameter log_line_prefix Set this value %m user=%u db=%d pid=%p: Then select Save. In Server parameters, confirm that the custom value is saved for log_line_prefix . Figure 1: Set log_line_prefix so pgBadger can correctly parse timestamp, user, database, and process ID from each log line. Prefix tokens Token Meaning %m Timestamp with milliseconds %u Username %d Database name %p Process ID After this change, log lines should look like this: Example log line 2026-06-22 19:00:00.070 UTC user=pgadmin db=highcpu pid=3805603: LOG: statement: SELECT 1 FROM pg_extension WHERE extname='pg_stat_statements' The matching pgBadger prefix for this log format is: Matching pgBadger prefix %m user=%u db=%d pid=%p: You will use this same value later in the pgBadger command. What good looks like: The server parameter is saved, and new PostgreSQL log lines begin with timestamp, user, database, and process ID fields that match the pgBadger prefix. Step 3: Enable Server logs for download This is also a one-time setup step. In the Azure portal, open your Flexible Server and go to Server logs. Enable: Portal setting Capture logs for download Set the retention period based on how long you want logs to remain available for download. For example, a 7-day retention period keeps logs available for download for 7 days. In Server logs, enable Capture logs for download and choose the retention window. Figure 2: Enable Capture logs for download and set a retention period long enough to cover the analysis window you want to inspect. What good looks like: After Server logs are enabled, hourly PostgreSQL log files appear in the Server logs blade and can be downloaded from the Azure portal. Once enabled, hourly log files appear in the Server logs blade. The files are named by date and hour, for example: Example log files postgresql_2026_06_22_19_00_00.log postgresql_2026_06_22_20_00_00.log Step 4: Download and organize the logs locally From the Server logs page, select the .log files for the time window you want to analyze and download them. For example, to analyze activity between 19:00 and 21:00 UTC, download: Example files to download postgresql_2026_06_22_19_00_00.log postgresql_2026_06_22_20_00_00.log On your local machine, create a folder for that analysis window. A simple convention is to use the Mon-DD format. Folder name Jun-22 Place the downloaded .log files inside that folder. Your local folder structure should look like this: Folder structure pgbadger-13.1/ pgbadger Jun-22/ postgresql_2026_06_22_19_00_00.log postgresql_2026_06_22_20_00_00.log Step 5: Generate the pgBadger report Open Git Bash from the folder where pgBadger is located. For example, if pgBadger is inside the pgbadger-13.1 folder, open Git Bash from that folder. # Action Command 1 Set the folder FOLDER=Jun-22 2 Confirm files ls -lh ./$FOLDER 3 Run pgBadger Use the full command below. Copy and run FOLDER=Jun-22 ls -lh ./$FOLDER perl -X ./pgbadger -f stderr \ --prefix '%m user=%u db=%d pid=%p:' \ ./$FOLDER/*.log \ -o ./$FOLDER/pgbadger-report.html Command breakdown Part of command Purpose perl -X ./pgbadger Runs pgBadger and suppresses non-critical Perl warnings. -f stderr Parses PostgreSQL stderr log files. --prefix '%m user=%u db=%d pid=%p:' Matches the log_line_prefix set on the server. ./$FOLDER/*.log Analyzes every .log file in the selected folder. -o ./$FOLDER/pgbadger-report.html Writes the HTML report into the same folder. When the command completes successfully, you should see output like this: Expected output Parsed 12134249 bytes of 12134249 (100.00%), queries: 26684, events: 83 LOG: Ok, generating html report... What good looks like: pgBadger finishes parsing the logs and creates pgbadger-report.html in the selected folder. Step 6: Open the report Open the generated report: Copy and run start ./$FOLDER/pgbadger-report.html The report opens in your default browser. The final report is created here: Generated report path Jun-22/pgbadger-report.html What the report can show The pgBadger report gives you a quick view into the workload shape for the selected log window. For example, in a sample run across two hourly log files, pgBadger summarized: Total number of queries. Number of unique normalized queries. Query traffic over time. Events such as errors and fatal messages. Session and connection patterns. Once the report opens, start with Global Stats to confirm the time range, total queries, normalized queries, and query peak. Figure 3: Start with Global Stats to validate the selected time range, total query count, normalized query count, and query peak. Query volume and normalized queries Many raw queries can often reduce to a smaller number of normalized query patterns. This helps identify whether the workload is spread across many different query shapes or dominated by a smaller set of repeated statements. Example: In this sample run, 26,684 queries reduced to 59 normalized query shapes. That suggests the workload is mostly a small set of repeated statements, which can help focus tuning effort. Traffic patterns The SQL Traffic section helps identify spikes, quiet periods, and workload changes over time. Figure 4: Use SQL Traffic to identify query spikes, quiet periods, and workload changes during the selected log window. Figure 5: Review the query breakdown to compare read vs. write volume and query-type distribution for the selected Server logs window. For example, if the report shows a steady baseline followed by a sharp spike, that spike can be correlated with application activity, batch jobs, synthetic tests, or operational events during the same time window. Query duration If query duration shows 0 ms or the slow query sections are empty, it usually means duration logging was not enabled when the logs were collected. In that case, pgBadger can still show query counts and events, but it cannot calculate the slowest queries, total execution time, average duration, or maximum duration. To unlock those timing sections, enable log_min_duration_statement , collect fresh logs, and rerun pgBadger. What pgBadger cannot infer from missing logs pgBadger reports are only as complete as the log data you provide. If PostgreSQL did not log duration, lock waits, temporary files, or autovacuum activity during the selected time window, pgBadger cannot reconstruct those details later. To analyze... Enable before collecting logs Slow queries log_min_duration_statement Lock waits log_lock_waits Temporary files log_temp_files Autovacuum activity log_autovacuum_min_duration Repeatable copy/paste block Reusable command block Change only FOLDER for each new analysis window. Copy and run FOLDER=Jun-22 ls -lh ./$FOLDER perl -X ./pgbadger -f stderr \ --prefix '%m user=%u db=%d pid=%p:' \ ./$FOLDER/*.log \ -o ./$FOLDER/pgbadger-report.html start ./$FOLDER/pgbadger-report.html For another date, change only this line: Update this value FOLDER=Jun-22 Examples: Example folder values FOLDER=Jun-23 FOLDER=Jul-01 FOLDER=Aug-15 Optional: Improve report quality pgBadger can only analyze the information captured in PostgreSQL logs. The default logs may be enough for query frequency, connection activity, and errors. For deeper performance troubleshooting, consider enabling additional logging parameters based on your scenario. Scenario Parameter Suggested value Notes Slow query analysis log_min_duration_statement 1000 Logs statements slower than 1 second. Short controlled test log_min_duration_statement 0 Logs every statement. Use carefully. Lock troubleshooting log_lock_waits on Helps identify lock waits. Temporary file analysis log_temp_files 0 Logs all temporary files. Autovacuum visibility log_autovacuum_min_duration 0 Useful during focused analysis. Useful parameters include: Recommended logging parameters log_lock_waits = on log_temp_files = 0 log_autovacuum_min_duration = 0 To capture query durations, configure: Duration logging log_min_duration_statement = 1000 This logs statements that run longer than 1000 milliseconds. For short test runs, you can temporarily use: Short test run only log_min_duration_statement = 0 Caution: Use log_min_duration_statement = 0 carefully on busy production servers. It logs every statement and can generate a large volume of logs. Duration matters: If duration logging is not enabled, pgBadger can still show query counts and events, but slowest-query, total duration, average duration, and maximum duration sections will be limited or empty. Common mistakes and quick fixes Symptom Likely cause Fix Report is empty Prefix mismatch Match --prefix with log_line_prefix . No duration data Duration logging was not enabled Set log_min_duration_statement before collecting logs. No files visible Server logs disabled or retention expired Enable capture and check retention. pgBadger command fails pgBadger is not in the current folder or path Run pgbadger -V to confirm installation. Common troubleshooting FAQs 1. Report is created but empty This usually means the pgBadger prefix did not match the actual log format. Check the first few lines: Copy and run head -5 ./$FOLDER/*.log Make sure the pgBadger --prefix matches the server’s log_line_prefix . 2. Report shows queries but no duration PostgreSQL logged statements but did not log durations. Enable one of the following, collect fresh logs, and rerun pgBadger: Parameter options log_min_duration_statement = 1000 # or temporarily for testing log_min_duration_statement = 0 3. No .log files are visible Confirm that Server logs are enabled: Portal setting Capture logs for download Also check the retention period. If the retention period has expired, older logs may no longer be available for download. 4. pgBadger command fails Confirm that pgBadger is available in the current folder or installed in your path. Copy and run pgbadger -V If you are running pgBadger from the local folder, use: Copy and run perl -X ./pgbadger Summary For customers already using Azure Database for PostgreSQL Flexible Server logs, the pgBadger workflow is straightforward: Install pgBadger. Configure log_line_prefix . Enable Server logs for download. Download the .log files. Place them in a local date-based folder. Run pgBadger with the matching prefix. Open pgbadger-report.html . Bottom line: Server logs give you the shortest path from Azure Database for PostgreSQL Flexible Server logs to a pgBadger report. Download the native .log files, run pgBadger with the matching prefix, and open the generated HTML report.

With the pg_ivm extension you can automatically maintain materialized views as the underlying data changes. This is particularly valuable for large datasets with small incremental changes that need real-time freshness, like dashboards, catalog analytics and SaaS usage reporting. We are pleased to announce the pg_ivm extension is now generally available in Azure Database for PostgreSQL. Learn more: pg_ivm. Security, Auditing & Identity Defender security assessments Preview Microsoft Defender Security Assessments for Azure Database for PostgreSQL enables continuous evaluation of your database security posture, helping identify vulnerabilities and misconfigurations across server and database configurations. Previously limited to reactive threat detection, in the latest preview release, Defender now provides proactive, risk-based insights through assessments tailored to PostgreSQL-specific best practices, delivering more relevant and actionable guidance. This helps you strengthen your security baseline, prioritize remediation, and align with best practices and compliance requirements. Learn more: https://aka.ms/Defender-Assessments-for-PG-Preview temporal_tables Extension Generally Available We’ve had many customer requests to support the temporal_tables extension, which provides built-in support for tracking and querying historical changes to data over time. Temporal tables are now generally available in Azure Database for PostgreSQL. With this extension enabled you can easily perform time-based queries, audit data changes, and maintain historical records without building custom tracking logic, simplifying application development and compliance scenarios. Learn more: temporal_tables Cross-tenant CMK Preview Azure Database for PostgreSQL now supports cross-tenant customer-managed keys (CMK) in public preview, allowing you to encrypt your data at rest using an Azure Key Vault key that resides in a separate Microsoft Entra tenant from the database service. This feature is designed for SaaS providers and enterprises that need to maintain strict separation of duties and ownership of encryption keys, enabling you to retain full control over key lifecycle management while PostgreSQL runs in a service provider’s tenant. Learn more: Data encryption at rest in Azure Database for PostgreSQL Automatic Entra token refresh libraries Preview We’re making it easier to use Entra ID authentication with Azure Database for PostgreSQL throughout the application stack by introducing new token refresh libraries for .NET, JavaScript, and Python. With Entra ID, access tokens are short-lived which can make managing their lifecycle complex in real-world applications. Developers need to be aware of token refresh and build additional handling around token expiration, connection retry, and session continuity. These new libraries remove that friction. By handling Entra token refresh seamlessly in the background, they allow applications to stay connected without interruption and with no custom logic required. The result is a simpler development experience and more resilient applications, especially for long-running or connection-heavy workloads. Across languages, the libraries provide a consistent and streamlined way to adopt secure, passwordless authentication, helping teams focus more on building their applications and less on managing authentication. Learn more: .NET, JavaScript, and Python. Operations, Maintenance & Monitoring New Powershell module: Az.PostgreSQLFlexibleServer Generally Available We’re excited to introduce the newly renamed Az.PostgreSQLFlexibleServer PowerShell module, delivering a streamlined experience for managing Azure Database for PostgreSQL with PowerShell. Building on the capabilities of the previous Az.PostgreSql module, the updated module aligns with the new features in the 2026-01-01 preview REST API. This module brings support for PostgreSQL 18, elastic clusters for scalable workloads and a range of enhancements designed to simplify management and improve performance. Whether you're provisioning new deployments or managing complex environments, this module ensures you can take full advantage of the latest platform capabilities directly from PowerShell. To learn more, visit our official documentation on PowerShell: Az.PostgreSql Module | Microsoft Learn More control over planned maintenance Generally Available We’ve seen many requests to provide more control when a maintenance update is applied to Azure Database for PostgreSQL.

Announcing general availability this week, we’re building on the existing System and Custom maintenance window options and adding new self-service maintenance capabilities to the Azure portal. You can now reschedule upcoming maintenance updates for up to two weeks and apply maintenance on demand at a time that suits you. You can also view scheduled maintenance and review your server’s maintenance history after updates are complete. These options help you better align maintenance with your business schedules, reduce disruption during critical workload periods, and minimize the need for support-driven deferral requests. CLI and API support are coming soon. Learn more: https://aka.ms/azure-postgres-reschedule-maintenance Pre-Upgrade validation checks Preview Major version upgrades are critical for staying current with PostgreSQL features, security updates, and performance improvements, but you often discover blockers only after starting the upgrade workflow. Pre-Upgrade Validation Checks lets you validate upgrade readiness before initiating the actual upgrade by running Azure-specific upgrade checks and PostgreSQL pg_upgrade --check validations independently. The shift is simple: you can identify and fix upgrade blockers before the upgrade window begins. The feature surfaces actionable issues across configurations, extensions, dependencies, replication slots, event triggers, and other upgrade-sensitive objects. You can fix blockers, re-run validation until all checks pass, and proceed with the upgrade with greater predictability. Learn more: https://aka.ms/pg-flex-upgrade-checks New Built-in Grafana dashboards Generally Available Grafana dashboards are now built directly into the Azure portal for Azure Database for PostgreSQL - no setup, no extra cost, and no separate service to manage.

Learning Bytes Create Azure Database for PostgreSQL elastic clusters with terraform: Elastic clusters in Azure Database for PostgreSQL let you scale PostgreSQL horizontally using a managed, multi‑node architecture. With Elastic cluster now generally available, you can provision and manage elastic clusters using infrastructure‑as‑code, making it easier to automate deployments, standardize environments, and integrate PostgreSQL into CI/CD workflows. Elastic clusters are a good fit when you need: Horizontal scale for large or fast‑growing PostgreSQL workloads Multi‑tenant applications or sharded data models Repeatable and automated deployments across environments The following example shows a basic Terraform configuration to create an Azure Database for PostgreSQL flexible server configured as an elastic cluster. resource "azurerm_postgresql_flexible_server" "elastic_cluster" { name = "pg-elastic-cluster" resource_group_name = <rg-name> location = <region> administrator_login = var.admin_username administrator_password = var.admin_password version = "17" sku_name = "GP_Standard_D4ds_v5" storage_mb = 131072 cluster { size = 3 } } Conclusion That’s a wrap for the February 2026 Azure Database for PostgreSQL recap. We’re continuing to focus on making PostgreSQL on Azure easier to build, operate, and scale whether that’s through better automation with Terraform, improved observability, or a smoother day‑to‑day developer and admin experience.
