pg_dump has historically assumed that default_with_oids affects only plain tables and not other relkinds. Conceivably we could make it apply to some newly invented relkind if we did so from the get-go, but changing the behavior for existing object types will break existing dump scripts. Add code comments warning about this interaction. Also, make sure that default_with_oids doesn't cause parse_utilcmd.c to think that CREATE FOREIGN TABLE will create an OID column. I think this is only a latent bug right now, since we don't allow UNIQUE/PKEY constraints in CREATE FOREIGN TABLE, but it's better to be consistent and future-proof.
