Same as now: if you have a unique index on 'em, they're unique within a
table; otherwise, no guarantee at all (once the system wraps around).

We should document this state of affairs better, of course, but I'm not
proposing to change it.  The point here is just to let people suppress
OIDs for tables that don't need them, and thereby postpone OID wraparound.
