The CVS logs show there was some confusion about applying the whole of
the pggist patch, so it's possible that this was an unintentional
omission.

Yes. I had been thinking of migrating one or more of the new contrib
GIST opclasses into the main distribution for 7.2, if only to be able to
create a regress test for GIST. Updating this old Berkeley code would
be another path to create/extend a GIST regress test. If you (or
someone else) have time to do that, it'd be great.
