UID and GID change
in !26 (merged) the docker file was changed to add
groupadd -g 1001 postgres && \
useradd -r -u 1001 -m --home-dir=/var/lib/postgresql --shell=/bin/bash -g postgres postgres && \
mkdir -p /var/lib/postgresql/data && \
chown -R postgres:postgres /var/lib/postgresql
this seems to break when changing the POSTGRES_USER
as part of the environment variables. I am getting an error of 'psql: FATAL: role "postgres" does not exist` but if I go back to prior to that change (13.6) I don't have the same issue.
