Hmm, that would be a different way of attacking the problem.  Not sure
offhand which is better, but it'd surely be worth considering both.

Note that collecting of dead-tuple counts requires input from aborted
transactions as well as successful ones.  I don't recall whether the
stats collector currently collects anything from aborted xacts; that
might or might not be a sticky point.
