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. NEWS: Apr 17, 2004 - Performance optimizing Jan 21, 2004 - add support for bytea, numeric, bit, varbit, inet/cidr Jan 17, 2004 - Reorganizing code and add support for char, varchar/text Jan 10, 2004 - btree_gist now support oid , timestamp with time zone , time with and without time zone, date , interval money, macaddr Feb 5, 2003 - btree_gist now support int2, int8, float4, float8 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;
