Especially if we start saving the 4 bytes that a NULL oid takes up in a
table tuple on disk.

Perhaps:

ALTER TABLE tab SET WITHOUT OIDS;

I think the reverse operation would really be impossible...? Unless we run
through the entire table and insert an oid for each row from the oid
counter?

Hell yeah.

By the way - I'm not saying I'll be implementing this any time soon!
