GiST indexes aren't really ready for prime time (no WAL logging and poor
concurrent behavior being the main gripes). I'm hesitant to make any of
the core SQL features depend on them until those issues are fixed.
Oleg and Teodor have made noises about doing something about those
problems, but I'm not sure it's at the top of their to-do lists ...
