MERGE feature is interesting. But specifically on the revoking CREATE permissions for the public (or default) schema, this is a step in the right direction. Some of the defaults in Postgres can be more secure. For example, the first time I use a POSTGRES_PASSWORD to configure a password, changing this password involves more steps than just changing the values of the ENV, because it doesn't take the changed value there after.

Structured logging with JSON is going to improve a lot of debugging, again a great productive change.

Also, any idea when the docker image for Postgres 15 will be available?

Looking at the Alpine docker file(s) for Postgres you might be able to use the one for the release candidate and set en environment variable of PGVERSION=15.0 which should use https://ftp.postgresql.org/pub/source/v15.0/ here.

You would need to figure out what the package name is on Debian (if it even exists yet?) it's currently set to ENV PG_VERSION 15~rc2-1.pgdg110+1

YMMV.
