From the discussion we had a few months ago, I don't think the no
RECHECK trick works with CVS tip anymore.
See my post on the "Remove lossy-operator RECHECK flag?" thread:
http://archives.postgresql.org/pgsql-hackers/2008-04/msg00847.php
and follow-ups.
That said, perhaps it's not the only problem you have but I thought it
was worth mentioning.
