ISTM that you are complaining because we never had an *fast* count(*)
and adding that now comes at a cost. Had it been there from day one with
the same overhead as we are talking about now, nobody would have
complained :-)
Anyways, your point is taken and it would be great if can make it configurable,
if not table level then at least globally.
