There isn't any "maybe" involved here. Follow Adrian's advice and
determine for sure exactly which database that subdirectory represents.
The subdirectory name will match the OID in the pg_database row.
It's possible for the same table OID to be in use in more than one
database, so the fact that you got a match to the other table doesn't
in itself prove you're looking at the right database.
