0f77636c2e Remove directory qualification in <ossp/uuid.h> because it's not always installed in ossp.
Workaround for when it is: include the ossp directory using --with-includes.

0fef38da21 Tweak hash index AM to use the new ReadOrZeroBuffer bufmgr API when fetching
pages it intends to zero immediately.  Just to show there is some use for that
function besides WAL recovery :-).
Along the way, fold _hash_checkpage and _hash_pageinit calls into _hash_getbuf
and friends, instead of expecting callers to do that separately.

6506a584cc Enable building contrib/xml2 if configured using --with-libxml.
If this breaks things due to missing libxslt, then I'll have to
revert it, but let's see if it breaks the buildfarm.

Workarounds in case libxslt is missing include:
. don't configure with libxml, or
. don't build contrib modules from the contrib Makefile (use the individual module Makefiles instead), or
. change the xml2 Makefile

e574f2a029 Enhance pgbench -l option to add timestamp. Patch contributed by Greg
Smith. Along with Japanese doc updation by Tasuo Ishii.

> This patch changes the way pgbench outputs its latency log files so that

7e96269a82 Various pgbench enhancements. Patch contributed by ITAGAKI Takahiro.
Also tweak README.pgbench/README.pgbench_jis:
  Remove history after pgbench was added to PostgreSQL contrib module.
  Those info was not only redundant since it has already been in CVS
  log, but also incomplete.
--------------------------------------------------------------------------
The attached is a patch to optimize contrib/pgbench using new 8.3 features.

- Use DROP IF EXISTS to suppress errors for initial loadings.
- Use a combination of TRUNCATE and COPY to reduce WAL on creating
  the accounts table.

Also, there are some cosmetic changes.

- Change the output of -v option from "starting full vacuum..."
  to "starting vacuum accounts..." in reflection of the fact.
- Shape duplicated error checks into executeStatement().


There is a big performance win in "COPY with no WAL" feature.
Thanks for the efforts!

37a609b27f Now that core functionality is depending on autoconf's AC_C_BIGENDIAN to be
right, there seems precious little reason to have a pile of hand-maintained
endianness definitions in src/include/port/*.h.  Get rid of those, and make
the couple of places that used them depend on WORDS_BIGENDIAN instead.

3e23b68dac Support varlena fields with single-byte headers and unaligned storage.
This commit breaks any code that assumes that the mere act of forming a tuple
(without writing it to disk) does not "toast" any fields.  While all available
regression tests pass, I'm not totally sure that we've fixed every nook and
cranny, especially in contrib.

e85a01df67 Clean up the representation of special snapshots by including a "method
pointer" in every Snapshot struct.  This allows removal of the case-by-case
tests in HeapTupleSatisfiesVisibility, which should make it a bit faster
(I didn't try any performance tests though).  More importantly, we are no
longer violating portable C practices by assuming that small integers are
distinct from all pointer values, and HeapTupleSatisfiesDirty no longer
has a non-reentrant API involving side-effects on a global variable.

There were a couple of places calling HeapTupleSatisfiesXXX routines
directly rather than through the HeapTupleSatisfiesVisibility macro.
Since these places had to be changed anyway, I chose to make them go
through the macro for uniformity.

Along the way I renamed HeapTupleSatisfiesSnapshot to HeapTupleSatisfiesMVCC
to emphasize that it's only used with MVCC-type snapshots.  I was sorely
tempted to rename HeapTupleSatisfiesVisibility to HeapTupleSatisfiesSnapshot,
but forebore for the moment to avoid confusion and reduce the likelihood that
this patch breaks some of the pending patches.  Might want to reconsider
doing that later.

95f6d2d209 Make use of plancache module for SPI plans. In particular, since plpgsql
uses SPI plans, this finally fixes the ancient gotcha that you can't
drop and recreate a temp table used by a plpgsql function.

Along the way, clean up SPI's API a little bit by declaring SPI plan
pointers as "SPIPlanPtr" instead of "void *".  This is cosmetic but
helps to forestall simple programming mistakes.  (I have changed some
but not all of the callers to match; there are still some "void *"'s
in contrib and the PL's.  This is intentional so that we can see if
anyone's compiler complains about it.)

754148d81f Add GIN support for pg_trgm. From Guillaume Smet <guillaume.smet@gmail.com>
with minor editorization by me.

Hstore improvements
* add operation hstore ? text - excat equivalent of exist()
* remove undocumented behaviour of contains operation with NULL value
* now 'key'::text=>NULL returns '"key"=>NULL' instead of NULL
* Add GIN support for contains and exist operations
* Add GiST support for exist operatiion
* improve regression tests

2afb01dbde Athough cube is a varlena type, nowhere was a detoasting of cube's value, so
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.

90d76525c5 Add resetStringInfo(), which clears the content of a StringInfo, and
fixup various places in the tree that were clearing a StringInfo by hand.
Making this function a part of the API simplifies client code slightly,
and avoids needlessly peeking inside the StringInfo interface.

9f652d430f Fix up several contrib modules that were using varlena datatypes in not-so-obvious
ways.  I'm not totally sure that I caught everything, but at least now they pass
their regression tests with VARSIZE/SET_VARSIZE defined to reverse byte order.

234a02b2a8 Replace direct assignments to VARATT_SIZEP(x) with SET_VARSIZE(x, len).
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.

8b4ff8b6a1 Wording cleanup for error messages. Also change can't -> cannot.
Standard English uses "may", "can", and "might" in different ways:

        may - permission, "You may borrow my rake."

        can - ability, "I can lift that log."

        might - possibility, "It might rain today."

Unfortunately, in conversational English, their use is often mixed, as
in, "You may use this variable to do X", when in fact, "can" is a better
choice.  Similarly, "It may crash" is better stated, "It might crash".

d4c6da1527 Allow GIN's extractQuery method to signal that nothing can satisfy the query.
In this case extractQuery should returns -1 as nentries. This changes
prototype of extractQuery method to use int32* instead of uint32* for
nentries argument.
Based on that gincostestimate may see two corner cases: nothing will be found
or seqscan should be used.

Per proposal at http://archives.postgresql.org/pgsql-hackers/2007-01/msg01581.php

are always emitted by bison-generated code. Patch from Magnus Hagander.
