What exactly image produces this error?

Fix error on create postgresql cluster:
  install: cannot change permissions of 'pg_stat_tmp': No such file or directory
  Error: /usr/lib/postgresql/15/bin/pg_ctl/usr/lib/postgresql/15/bin/pg_ctl start -D /var/lib/postgresql/15/main-l /var/log/postgresql/postgresql-15-main.log --wait -s -o  -cconfig_file="/etc/postgresql/15/main/postgresql.conf"  exited withstatus 1:

I have tested with the new docker image:

$ docker images | grep pgwatch2
cybertec/pgwatch2-postgres   latest            d4e17244e72e   26 hours ago   1.17GB

With docker volumes ...

  pw2:

it looks ok.
Just one error:

BEGIN

psql:/pgwatch2/metrics/00_helpers/get_stat_statements/9.2/metric.sql:36: ERROR:  column s.total_time does not exist
LINE 11:    s.query, s.calls, s.total_time, s.rows, s.shared_blks_hit...

ROLLBACK

See here my commit 1e5d0582f9

But with volumes as local directory,

    volumes:
      - ./data/pg:/var/lib/postgresql
      - ./data/grafana:/var/lib/grafana
      - ./data/pw2:/pgwatch2/persistent-config

i still get the same errors.
