[BUG] Error starting postorius with postgres: initialization of _psycopg raised unreported exception

[Skyr]

Tag/version of Container Images: 0.4.6

settings_local.py just empties the MAILMAN_WEB_SOCIAL_AUTH array.

When starting the postorius image, it immediately crashes with the following output:

Postgres is up - continuing
Copying settings_local.py ...

SystemError: initialization of _psycopg raised unreported exception

Comparing the 0.4.6 image to 0.4.5, I noticed that the Python version changed from 3.10 to 3.11. So this might be related to some Python version mismatch like described here: psycopg/psycopg2#1144

Which version of psycopg2 and postgresql are you using? We recently bumped the version of postgresql in our compose file to 12 from 11 for some bugs I remember seeing.
