Hi there,
we are in the same situation, yet on a standalone setup. shared/standalone/log/var-log/ does not display any files at all, however after entering the container, we see identical results:
root@pulp-discourse-iptools:/var/www/discourse# tail -n 3 /var/log/postgres/current
2021-10-13 18:33:04.027 GMT [917] LOG: skipping missing configuration file "/shared/postgres_data/postgresql.auto.conf"

2021-10-13 18:33:04.028 UTC [917] HINT: The server must be started by the user that owns the data directory.

However, that still looks weird:
root@pulp-discourse-iptools:/var/www/discourse# ls -alF /shared | grep postgres_
drwxr-xr-x 2 postgres postgres 6 Apr 3 2019 postgres_backup/

drwxrwsr-x 4 Debian-exim ssh 60 Oct 13 17:56 postgres_run/
In order to be more safe than sorry, we switched back to "templates/postgres.10.template.yml" in app.yml and currently only aim to bring the old instance up again.
Maybe it is sensible to share that we are already on the most recent commit of https://github.com/discourse/discourse_docker.git, after switching to the main branch. However, because the rebuild did not succeed, this probably has no impact when starting the previous image, right?
If anyone has any idea how to resolve this situation, we would be very grateful. Otherwise, we might come back with further reports.
With kind regards,
Andreas.
