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.
