For the purpose that Greg is suggesting, these would have no advantage over min() or max() --- since the system wouldn't know how to optimize them --- and they'd be considerably less standard. So my inclination would be to say it's a waste of effort. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
