On machines where gettimeofday is slow (and last I heard there were
still lots of them), any such thing would be a disaster
performance-wise. I'm still afraid to add more gettimeofday's into the
query parse/plan/execute code path, even though it would greatly ease
the problem of figuring out whether re-planning is worthwhile.
