PL Extensions

Hi, my name is Dirk, i am a first timer here, so i am not fully sure this post/question is right here. If not please let me know of a better place to ask this question. Thank you 🙂

Here the question: we are planning to use PostgreSQL on Azure. We expect to do a bit of scripting in trigger functions as part of an ELT process. Was thinking about Perl since some functions require string Base64 encoding and XML parsing. In the documentation about Postgres on Azure I could see only PL/SQL as a supported extension, nothing about PL/Perl. Is this correct?

Would be great if someone could confirm this (or better yet, tell me that Perl is actually supported)!

Thank you,

Dirk
