The 2-Minute Rule for pgauto
If $PGDATA is really a mountpoint to get a filesystem, adjust it to get a Listing while in the mounted filesystem. One example is: if a filesystem is mounted to /var/lib/psql/data and $PGDATA is set to /var/lib/pgsql/data, change $PGDATA to /var/lib/pgsql/information/information.
