Postgres upgrade

[HubbeKing]

We should upgrade from Postgres 12 to a more recent version, 12 is getting its final release on November 14th 2024 and is EOL after that.

• https://www.postgresql.org/support/versioning/
• https://endoflife.date/postgresql
• https://www.postgresql.org/docs/current/upgrading.html

13 would of course work, but we should probably do this after DB and just go right up to 16 or 17.
