I don't think we want user authentication driven off of actual tables.
That would mean paying *all* the costs of backend launch before we could
reject an invalid connection request.
It might be possible to do something with a flat file as an intermediary
between the postmaster and the tables that are the master data. We
already do this for pg_shadow passwords, and I've been thinking of
proposing that we add a flat file for the database name -> OID mapping
so we could get rid of the horrid hack that is GetRawDatabaseInfo().
Per-database flat files would be a bit messy though.
