I know Oleg has been discussing quad trees for years now, so SP-GIST
sounds like a great feature.
The docs on SP-GIST simply suggest people read the code, which is way
below our normal standard of documentation.
CREATE INDEX contains no examples involving SP-GIST indexes.
It seems likely that the first thing a user will ask is When can I use
it? How do I create one? When should I use it in comparison with
existing methods?
ISTM that if we mention this as a major feature in 9.2, and I think we
should, that there should be something more about these in the shared
docs.
