I think the only action called for is some improvement in the
documentation. Right now the docs are not honest about the state
of any of the non-btree index methods. Ain't none of 'em ready
for prime time IMHO. GIST is the only one that's getting any
development attention --- and probably the only one that deserves
it, given limited resources. Hash offers no compelling advantage
over btree AFAICS, and rtree is likewise dominated by GIST (or would
be, if we shipped rtree-equivalent GIST opclasses in the standard
distribution).
I do not like "throw an elog" as a substitute for documentation.
