Neil Conway 36ab600511 Cleanup of GiST extensions in contrib/: now that we always invoke GiST
methods in a short-lived memory context, there is no need for GiST methods
to do their own manual (and error-prone) memory management.

This is a B-Tree implementation using GiST that supports the int2, int4,
int8, float4, float8 timestamp with/without time zone, time
with/without time zone, date, interval, oid, money, macaddr, char,
varchar/text, bytea, numeric, bit, varbit and inet/cidr types.

All work was done by Teodor Sigaev (teodor@stack.net) , Oleg Bartunov
(oleg@sai.msu.su), Janko Richter (jankorichter@yahoo.de).
See http://www.sai.msu.su/~megera/postgres/gist for additional
information.

NOTICE:
     This version will only work with PostgreSQL version 7.4 and above
     because of changes in the system catalogs and the function call
     interface.
     
     If you want to index varchar attributes, you have to index using
     the function text(<varchar>):
     Example:
       CREATE TABLE test ( a varchar(23) );
       CREATE INDEX testidx ON test USING GIST ( text(a) );


INSTALLATION:

  gmake
  gmake install
  -- load functions
  psql <database> < btree_gist.sql

REGRESSION TEST:

   gmake installcheck

EXAMPLE USAGE:

   create table test (a int4);
   -- create index
   create index testidx on test using gist (a);
   -- query
   select * from test where a < 10;
