Or two couples KB smaller, if we abandoned the idea that pg_proc OIDs
must not collide with those in any other catalog, and we renumbered all
functions to start at OID 1 or so. duplicate_oids would complain about
that, though, I suppose ... and nobody who has ever hardcoded a function
OID would love this idea much.
