I thought about that for a bit while working on the knngist patch, but
couldn't really see any useful application.  In particular, I don't see
a way to shoehorn + and - in there as ordering operators.  They don't
match the structure.  The RANGE problem wants to add operators that are
somehow related to a btree's operators, but they're not related in the
way that knngist uses.
