Tom Lane 234a02b2a8 Replace direct assignments to VARATT_SIZEP(x) with SET_VARSIZE(x, len).
Get rid of VARATT_SIZE and VARATT_DATA, which were simply redundant with
VARSIZE and VARDATA, and as a consequence almost no code was using the
longer names.  Rename the length fields of struct varlena and various
derived structures to catch anyplace that was accessing them directly;
and clean up various places so caught.  In itself this patch doesn't
change any behavior at all, but it is necessary infrastructure if we hope
to play any games with the representation of varlena headers.

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;
