But they are not in same table, are they? I mean if you select on base table, how do you expect primary key constraint to be held against n child tables? I dunno what standard says about this. But as long as, select from child table on primary key does not return duplicate row, I wouldn't worry. This can be a really annoying issue for somebody. But I would advice him/her to work on table design rather than proposing it as a defect in PG. Shridhar
