If you can determine which table is being inserted/updated when this happens (admittedly the message is not being helpful), REINDEX should fix it. Did you have a system crash before this started? Running something newer than 8.1.4 would be advisable anyway. I seem to recall that we fixed at least one bug that could produce this symptom, though I don't see anything specifically about it in the 8.1 CVS logs. regards, tom lane
