Is there somewhere a note, which postgresql db versions are supported? Would be great to have something for each released discourse version - especially if a postgresql version is no longer supported.

Postgres is bundled in with the Docker container for Discourse, so this is generally hands-off. The Discourse team upgrades the Postgres version as new releases come out and they are properly tested. The most recent upgrade was to version 13. You can see the details of that upgrade here: …

Can it be used with discourse? Will there be any migration steps required for the database itself? (aside from the global migra…

PostgreSQL 13 is still the officially supported version, with version 13.15 being released last month and still supported. We have a good number of sites running version 15, and that is a known working version that we plan on shipping an update for self-hosted users eventually. Version 16 is not w…
