I've seen no demonstration of a need for *any* of them, actually, and am pretty dubious that we want to add so much collection overhead. At least not without a major redesign of the stats reporting mechanism. If we just drop in another seven counters, we'll create an immediate 50% increase in the stats-file I/O volume, even when no vacuuming is happening at all. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
