Yes, I have always liked CLUSTER with full text searches because you are
usually hitting multiple rows with a single equaltiy restriction, and
CLUSTER puts all the hits on the same page.

If you look in contrib/fulltextindex, you will see mention of CLUSTER in
the README.  It may make sense to add that to your documentation.

Also, is there any value to contrib/fulltextindex now that we have
contrib/tsearch?
