I'm tired, but I thought we did. Yeah, probably. It's the kind of thing where the call is close enough that it might be made differently by different people. After thinking about it for a bit, the only downside I can think of is that throwing an error might create an unexpected corner case for code that computes a LIMIT value on-the-fly and might sometimes come up with a slightly negative value. But you could always do LIMIT greatest(whatever, 0) so that seems like a weak argument. regards, tom lane
