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.

Please, apply attached patch, it solves the problem.

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.

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.

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

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.

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.

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

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

! #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?

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.

regression tests for the GiST changes ... this should be integrated into
the regular regression tests similar to Vadim's SPI contrib stuff ...
