Something along that line, probably.

OIDs aren't standard, so the standards are hardly likely to help us
decide how they should work.
I think the really critical choice here is how much backwards
compatibility we want to keep. The most backwards-compatible way,
obviously, is OIDs on by default and things work exactly as they
do now. But if we were willing to bend things a little then some
interesting possibilities open up. One thing I've been wondering
about is whether an explicit WITH OIDS spec ought to cause automatic
creation of a unique index on OID for that table. ISTM that any
application that wants OIDs at all would want such an index...
