Neil Conway 48fb696753 Fix a number of syntax errors in contrib modules' uninstall scripts.
Most of the changes add the mandatory USING clause to DROP OPERATOR
CLASS statements.  DROP TYPE is now DROP TYPE CASCADE; without
CASCADE a DROP TYPE fails due to the circular dependency on the
type's I/O functions.  The DROP FUNCTION statements for the I/O
functions have been removed, as DROP TYPE CASCADE removes them
automatically. Patch from Michael Fuhr.

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

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;
