pgsql: Solve the problem of OID collisions by probing for duplicate OIDs

-----------
Solve the problem of OID collisions by probing for duplicate OIDs
whenever we generate a new OID. This prevents occasional duplicate-OID
errors that can otherwise occur once the OID counter has wrapped around.
Duplicate relfilenode values are also checked for when creating new
physical files. Per my recent proposal.
