Depends on the the table, I'd say. Having toast tables have 64bit ids, and not advance the oid counter, would be quite the advantage over the current situation. Toasting performance craters once the oid counter has wrapped. But obviously there are upgrade problems there - presumably we'd need 'narrow" and 'wide' toast tables, or such.
