[Please reply to me directly as I only read this list sporadically.]

Has anybody thought about doing the work to fully implement r-trees
for all of the geometric types?  In particular, I'd be interested in
being able to index `point's rather than `box'es, and have the
optimizer decide to use the index for queries of the form `coord @
circle(coord2, some-radius)' or `coord @ box(coord2, coord3)'.

More complete indexing for geometric types?
