Most system catalogs use OIDs as primary keys.  So they cannot just
disappear.  But on user tables, there's not a lot of use for them IMHO.

There's no internal row id on Postgres; having one would mean more
storage requirements.  If you want one, you know where to get it ... if
not, you may as well save the space.
