1. Reworked patch from Andrey Oktyabrski (ano@spider.ru) with
      functions: icount, sort, sort_asc, uniq, idx, subarray
      operations: #, +, -, |, &

FUNCTIONS:

  int   icount(int[]) - the number of elements in intarray
  int[] sort(int[], 'asc' | 'desc') - sort intarray
  int[] sort(int[]) - sort in ascending order
  int[] sort_asc(int[]),sort_desc(int[]) - shortcuts for sort
  int[] uniq(int[]) - returns unique elements
  int   idx(int[], int item) - returns index of first intarray matching element
                               to item, or '0' if matching failed.
  int[] subarray(int[],int START [, int LEN]) - returns part of intarray
                               starting from element number START (from 1)
                               and length LEN.
OPERATIONS:

  int[] && int[]  - overlap - returns TRUE if arrays has at least one common elements.
  int[] @  int[]  - contains - returns TRUE if left array contains right array
  int[] ~ int[]   - contained - returns TRUE if left array is contained in right array
  # int[]         - return the number of elements in array
  int[] + int     - push element to array ( add to end of array)
  int[] + int[]   - merge of arrays (right array added to the end of left one)
  int[] - int     - remove entries matched by right argument from array
  int[] - int[]   - remove left array from right
  int[] | int     - returns intarray - union of arguments
  int[] | int[]   - returns intarray as a union of two arrays
  int[] & int[]   - returns intersection of arrays

ea4686e3e1 Implement CREATE/DROP OPERATOR CLASS. Work still remains: need more
documentation (xindex.sgml should be rewritten), need to teach pg_dump
about it, need to update contrib modules that currently build pg_opclass
entries by hand.  Original patch by Bill Studenmund, grammar adjustments
and general update for 7.3 by Tom Lane.

74a8af099f Please apply attached patch to contrib/intarray (7.2, 7.3).
Fixed bug with '=' operator for gist__int_ops and
     define '=' operator for gist__intbig_ops opclass.
     Now '=' operator is consistent with standard 'array' type.

     Thanks Achilleus Mantzios for bug report and suggestion.

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.

92288a1cf9 Change made to elog:
o  Change all current CVS messages of NOTICE to WARNING.  We were going
to do this just before 7.3 beta but it has to be done now, as you will
see below.

o Change current INFO messages that should be controlled by
client_min_messages to NOTICE.

o Force remaining INFO messages, like from EXPLAIN, VACUUM VERBOSE, etc.
to always go to the client.

o Remove INFO from the client_min_messages options and add NOTICE.

Seems we do need three non-ERROR elog levels to handle the various
behaviors we need for these messages.

Regression passed.

56f5dc9078 Remove bogus pg_amop insertion commands, per discussion of 25-Oct.
No change in results of script, but perhaps less confusion for people
reading it.

Changes:

 1. Added support for boolean queries (indexable operator @@, looks like
       a @@ '1|(2&3)'
 2. Some code cleanup and optimization

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.

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.

bf56f0759b Make OIDs optional, per discussions in pghackers. WITH OIDS is still the
default, but OIDS are removed from many system catalogs that don't need them.
Some interesting side effects: TOAST pointers are 20 bytes not 32 now;
pg_description has a three-column key instead of one.

Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey
has some usefulness; pg_dump dumps comments on indexes, rules, and
triggers in a valid order.

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.

0bfc64b387 Looks okay in a quick glance, except error message spelling is poor:
! #define ARRISNULL(x) ( (x) ? ( ( ARR_NDIM(x) == NDIM ) ? ( ( ARRNELEMS( x ) )
? 0 : 1 ) : ( ( ARR_NDIM(x) ) ? (elog(ERROR,"Array is not one-dimentional: %d di
mentions", ARR_NDIM(x)),1) : 1 ) ) : 1 )

Should be "one-dimensional" and "dimensions".  Bruce, would you fix that
when you apply it?

558fae16e3 The attached patch enables the contrib subtree to build cleanly under
Cygwin with the possible exception of mSQL-interface.  Since I don't
have mSQL installed, I skipped this tool.

Except for dealing with a missing getopt.h (oid2name) and HUGE (seg),
the bulk of the patch uses the standard PostgreSQL approach to deal with
Windows DLL issues.

I tested the build aspect of this patch under Cygwin and Linux without
any ill affects.  Note that I did not actually attempt to test the code
for functionality.

The procedure to apply the patch is as follows:

    $ # save the attachment as /tmp/contrib.patch
    $ # change directory to the top of the PostgreSQL source tree
    $ patch -p0 </tmp/contrib.patch

d08741eab5 Restructure the key include files per recent pghackers discussion: there
are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively.  By default, only include files meant for frontend use are
installed into the installation include directory.  There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.
