In all plausible test cases you should be able to know the total number of tuples being sorted independently. Counting the tuples processed in each run would require extra per-tuple overhead, which I'd rather avoid until proven necessary. The total-data-volume aspect may or may not be interesting, not sure yet. Let's see what we can learn from the present low-impact patch. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
