doing some digging at berkeley, i found the original pggist patch file
that created the gist access method & gist_box_ops opclass (among
others). i'm assuming that patch was the basis for what was originally
introduced, so i don't know why it didn't get included with everything
else. it looks like there are a lot of calls to internal postgresql box
comparison functions that would need to get converted to the new calling
convention, but it should be pretty straightforward to get it to work
with a recent version of postgresql. it does seem pretty silly to have
it in there if you don't have any built-in way of using it, if for no
other reason than to be able to test if the feature even works.
