We just released new version of contrib/btree_gist 

(7.3 and current CVS) with support of int8, float4, float8
in addition to int4. Thanks Janko Richter for contribution.

This is B-Tree implementation using GiST for int4 and
This is B-Tree implementation using GiST for int4, int8, float4, float8
timestamp types.
All work was done by Teodor Sigaev (teodor@stack.net) and Oleg Bartunov
(oleg@sai.msu.su). See http://www.sai.msu.su/~megera/postgres/gist
for additional information.
NEWS:
Feb 5, 2003 - btree_gist now support int8, float4, float8 !
Thank Janko Richter <jankorichter@yahoo.de> for
contribution.
NOTICE:
This version will works only with postgresql version 7.2 and above
This version will works only with postgresql version 7.3 and above
because of changes in interface of function calling and in system
tables.
