27a54ae282 Opclasses live in namespaces. I also took the opportunity to create
an 'opclass owner' column in pg_opclass.  Nothing is done with it at
present, but since there are plans to invent a CREATE OPERATOR CLASS
command soon, we'll probably want DROP OPERATOR CLASS too, which
suggests that a notion of ownership would be a good idea.

17cc78ef01 To fix the perpetually broken makefiles in the contrib tree, I have
written a generic framework of rules that the contrib makefiles can
use instead of writing their own each time.  You only need to set a few
variables and off you go.

a54075a6d6 Update GiST for new pg_opclass arrangement (finally a clean solution
for haskeytype).  Update GiST contrib modules too.  Add linear-time split
algorithm for R-tree GiST opclass.
From Oleg Bartunov and Teodor Sigaev.

f933766ba7 Restructure pg_opclass, pg_amop, and pg_amproc per previous discussions in
pgsql-hackers.  pg_opclass now has a row for each opclass supported by each
index AM, not a row for each opclass name.  This allows pg_opclass to show
directly whether an AM supports an opclass, and furthermore makes it possible
to store additional information about an opclass that might be AM-dependent.
pg_opclass and pg_amop now store "lossy" and "haskeytype" information that we
previously expected the user to remember to provide in CREATE INDEX commands.
Lossiness is no longer an index-level property, but is associated with the
use of a particular operator in a particular index opclass.

Along the way, IndexSupportInitialize now uses the syscaches to retrieve
pg_amop and pg_amproc entries.  I find this reduces backend launch time by
about ten percent, at the cost of a couple more special cases in catcache.c's
IndexScanOK.

Initial work by Oleg Bartunov and Teodor Sigaev, further hacking by Tom Lane.

initdb forced.

13923be7c8 1. null-safe interface to GiST
(as proposed in http://fts.postgresql.org/db/mw/msg.html?mid=1028327)

2. support for 'pass-by-value' arguments - to test this
   we used special opclass for int4 with values in range [0-2^15]
   More testing will be done after resolving problem with
   index_formtuple and implementation of B-tree using GiST

3. small patch to contrib modules (seg,cube,rtree_gist,intarray) -
   mark functions as 'isstrict' where needed.

7aac048b59 Attached is a patch to deal with the ones that I missed the first time
around.  I tested this patch under Cygwin and Linux.

Note that I only changed dblink's Makefile in the most minimal way
to fix the link problem under Cygwin (i.e., use the link rule from
Makefile.shlib instead).  dblink's Makefile should probably be further
patched to be consistent with the other PostgreSQL Makefiles.
