boxes. Change interface to user-defined GiST support methods union and
picksplit. Now instead of bytea struct it used special GistEntryVector
structure.

datatype; the generic array comparators added in 7.4 supersede this.
Per report and patch from Korea PostgreSQL Users' Group.

$Header: -> $PostgreSQL Changes ...

1 intarray: bugfix for int[]-int[] operation
2 intarray: split _int.c to several files (_int.c now is unused)
3 ntarray (gist__intbig_ops opclass): use special type for index storage
4 ltree (gist__ltree_ops opclass), intarray (gist__intbig_ops): optimize
GiST's
penalty and picksplit interface functions, now use Hemming distance.

docs that CLIENT/LOG_MIN_MESSAGES now controls debug_* output location.
Doc changes included.

only remnant of this failed experiment is that the server will take
SET AUTOCOMMIT TO ON.  Still TODO: provide some client-side autocommit
logic in libpq.

7.3 and current CVS

to MemSet is a performance boost.

it automatically now on regression session startup.

Create objects in public schema.

Make spacing/capitalization consistent.

Remove transaction block use for object creation.

Remove unneeded function GRANTs.

Please, apply attached patch, it solves the problem.

Teodor Sigaev

for contrib/intarray.

The cause was that the library uses its own function to construct a new
array, new_intArrayType, and that function did not set the new array
struct attribute elemtype.

Joe Conway

already fixed by You. However there were a few left and attached patch
should fix the rest of them.

I used StringInfo only in 2 places and both of them are inside debug
ifdefs. Only performance penalty will come from using strlen() like all
the other code does.

I also modified some of the already patched parts by changing
snprintf(buf, 2 * BUFSIZE, ... style lines to
snprintf(buf, sizeof(buf), ... where buf is an array.

with OPAQUE, as per recent pghackers discussion.  I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...

   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

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.

     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.

Oleg Bartunov

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.

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.

No change in results of script, but perhaps less confusion for people
reading it.

 1. gist__int_ops is now without lossy
 2. added sort entry in picksplit

Oleg Bartunov

Changes:

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

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.
