By when, is serial and the OIDs expected to be converted to int8 or even int6 for that matter rather than int4.
Also, what all transactions consume OIDs. Is it true that every update, select and delete also consume OIDs or only objects created (including tables, view, rows, etc.) consume them. Even if all other transactions consume OIDs, isnt that a waste... Shouldnt OIDs be used simply to identify the objects.
