calling convention. cube_inter and cube_distance could attempt to pfree
their input arguments, and cube_dim returned a value from a struct it
might have just pfree'd (which would only really cause a problem in a
debug build, but it's still wrong). Per bug #4208 and additional code
reading.
In HEAD and 8.3, I also made a batch of cosmetic changes to bring these
functions into line with the preferred coding style for V1 functions,
ie declare and fetch all the arguments at the top so readers can easily
see what they are.
"consistent" functions, and remove pg_amop.opreqcheck, as per recent
discussion. The main immediate benefit of this is that we no longer need
8.3's ugly hack of requiring @@@ rather than @@ to test weight-using tsquery
searches on GIN indexes. In future it should be possible to optimize some
other queries better than is done now, by detecting at runtime whether the
index match is exact or not.

from the other string-category types; this eliminates a lot of surprising
interpretations that the parser could formerly make when there was no directly
applicable operator.
Create a general mechanism that supports casts to and from the standard string
types (text,varchar,bpchar) for *every* datatype, by invoking the datatype's
I/O functions. These new casts are assignment-only in the to-string direction,
explicit-only in the other, and therefore should create no surprising behavior.
Remove a bunch of thereby-obsoleted datatype-specific casting functions.
The "general mechanism" is a new expression node type CoerceViaIO that can
actually convert between *any* two datatypes if their external text
representations are compatible. This is more general than needed for the
immediate feature, but might be useful in plpgsql or other places in future.
This commit does nothing about the issue that applying the concatenation
operator || to non-text types will now fail, often with strange error messages
due to misinterpreting the operator as array concatenation. Since it often
(not always) worked before, we should either make it succeed or at least give
a more user-friendly error; but details are still under debate.

fix it. Add macroses DatumGetNDBOX, PG_GETARG_NDBOX and PG_RETURN_NDBOX.
Backpatch for 8.2 too.
Previous versions use version 0 calling conventions. And fmgr code detoast
values for user-defined functions.
Get rid of VARATT_SIZE and VARATT_DATA, which were simply redundant with
VARSIZE and VARDATA, and as a consequence almost no code was using the
longer names. Rename the length fields of struct varlena and various
derived structures to catch anyplace that was accessing them directly;
and clean up various places so caught. In itself this patch doesn't
change any behavior at all, but it is necessary infrastructure if we hope
to play any games with the representation of varlena headers.
Greg Stark and Tom Lane
Update the calling convention for all external facing functions. By
external facing, I mean all functions that are directly referenced in
cube.sql. Prior to my update, all functions used the older V0 calling
convention. They now use V1.
New Functions:
cube(float[]), which makes a zero volume cube from a float array
cube(float[], float[]), which allows the user to create a cube from
two float arrays; one for the upper right and one for the lower left
coordinate.
cube_subset(cube, int4[]), to allow you to reorder or choose a subset of
dimensions from a cube, using index values specified in the array.

* new split algorithm (as proposed in http://archives.postgresql.org/pgsql-hackers/2006-06/msg00254.php)
* possible call pickSplit() for second and below columns
* add spl_(l|r)datum_exists to GIST_SPLITVEC -
pickSplit should check its values to use already defined
spl_(l|r)datum for splitting. pickSplit should set
spl_(l|r)datum_exists to 'false' (if they was 'true') to
signal to caller about using spl_(l|r)datum.
* support for old pickSplit(): not very optimal
but correct split
* remove 'bytes' field from GISTENTRY: in any case size of
value is defined by it's type.
* split GIST_SPLITVEC to two structures: one for using in picksplit
and second - for internal use.
* some code refactoring
* support of subsplit to rtree opclasses
TODO: add support of subsplit to contrib modules
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.

it this way already, while others used not-too-reliable sed hacks in
the Makefiles. It's all nice and consistent now.
more compliant with the error message style guide. In particular,
errdetail should begin with a capital letter and end with a period,
whereas errmsg should not. I also fixed a few related issues in
passing, such as fixing the repeated misspelling of "lexeme" in
contrib/tsearch2 (per Tom's suggestion).
external projects, we should be careful about what parts of the GiST
API are considered implementation details, and which are part of the
public API. Therefore, I've moved internal-only declarations into
gist_private.h -- future backward-incompatible changes to gist.h should
be made with care, to avoid needlessly breaking external GiST extensions.
Also did some related header cleanup: remove some unnecessary #includes
from gist.h, and remove some unused definitions: isAttByVal(), _gistdump(),
and GISTNStrategies.

catch possible worse errors in future.
yy_fatal_error() call results in elog(ERROR) not exit(). This was
already fixed in the main lexer and plpgsql, but extend same technique
to all the other dot-l files. Also, on review of the possible calls
to yy_fatal_error(), it seems safe to use elog(ERROR) not elog(FATAL).

we will probably want to adopt the newer message spelling ... but not yet.

Note: I didn't change the build rules for bootstrap, ecpg, or plpgsql
grammars, since these do not affect regression test results.

(usually bison output files), not as standalone files. This hack
works around flex's insistence on including <stdio.h> before we are
able to include postgres.h; postgres.h will already be read before
the compiler starts to read the flex output file. Needed for largefile
support on some platforms.

Recent changes include changing the subscript in one place I forgot
in the previous bugfix patch. A couple of added regression tests, which
should help catch this mistake if it reappears.
I also put in a limit of 100 dimensions in cube_large and cube_in to
prevent making it easy to create very large cubes. Changing one define
in cubedata.h will raise the limit if some needs more dimensions.

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.

diffs to 7.3-devel and may not be applicable to 7.2. I have included a
change covered by a previous bugfix patch I submitted (the problem with
-.1 not being accepted by cube_in). It does not include a fix for the
potential buffer overrun issue I reported for cube_yyerror in
cubeparse.y.

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

suggests that a notion of ownership would be a good idea.
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.
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.

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

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

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.
