Change default value for postgres_data_path

/var/lib/postgresql/data/pgdata
to
/var/lib/pgsql/data/pgdata

postgres 15 uses a different location for
postgres data directory.

Fixes issue were database was not being written
to the mounted in volume, and if the postgres
container restarted, data would be lost.
