Odd..  I could have sworn I saw a difference in the query generated,
but perhaps I just assumed it was reordered, since it ends up ordered
differently in the actual plans:

8.2: http://explain.depesz.com/s/449
9.1: http://explain.depesz.com/s/03O

Increasing the cost of pg_table_is_visible() caused it to move that test
to the end again (under 9.1), which improved the performance (though I'm
sure having a usable index would help a great deal more..).
Thanks,
