Tom-
I don't really have time to follow up at this moment, but I think this would
be interesting to look into, so I'll plan to dig into it over the
Thanksgiving Holiday when I'll have a little time free to follow up on some
fun projects. Your pointers should let me get into it pretty quickly.
In the meantime, I'll just set up a cron job that runs behind my nightly
analyze to put the correct numbers into pg_statistic on the tables that this
affects.
Thanks-
