Tom Lane 313ed1ed94 Fix (hopefully for the last time) problems with datetime values displaying
like '23:59:60' because of fractional-second roundoff problems.  Trying
to control this upstream of the actual display code was hopeless; the right
way is to explicitly round fractional seconds in the display code and then
refigure the results if the fraction rounds up to 1.  Per bug #1927.

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).

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;
