Well, AFAICT we have agreed in this thread to kick up the default and
maximum stats targets by a factor of 10 for 8.4. If there's anything
to your thesis that a bigger sample size will help, that should already
make a noticeable difference. I'm inclined to wait for some field
experience with 8.4 before we start making fundamental changes to the
ANALYZE code.
