As Bruce mentioned, this is due to the conflict among changes we made.
Included patches should fix the problem(I changed all MB to
MULTIBYTE). Please let me know if you have further problem.

P.S. I did not include pathces to configure and gram.c to save the
file size(configure.in and gram.y modified).

e0058b6172 Theses buffer leaks are caused by indexes that are kept open between
calls. Outside a transaction, the backend detects them as buffer
leaks; it sends a NOTICE, and frees them. This sometimes cause a
segmentation fault (at least on Linux). These indexes are initialized
on the first lo_read/lo_write/lo_tell call, and (normally) closed
on a lo_close call.  Thus the buffer leaks appear when lo direct
access functions are used, and not with lo_import/lo_export functions
(libpq version calls lo_close before ending the command, and the
backend version uses another path).

The included patches (against recent snapshot, and against 6.3.2)
cause indexes to be closed on transaction end (that is on explicit
'END' statment, or on command termination outside trasaction blocks),
thus preventing the buffer leaks while increasing performance inside
transactions. Some (all?) 'classic' memory leaks are also removed.

I hope it will be ok.

cb7cbc16fa Hi, here are the patches to enhance existing MB handling. This time
I have implemented a framework of encoding translation between the
backend and the frontend. Also I have added a new variable setting
command:

SET CLIENT_ENCODING TO 'encoding';

Other features include:
	Latin1 support more 8 bit cleaness

See doc/README.mb for more details. Note that the pacthes are
against May 30 snapshot.

68f9c9819b Remove added NullProc define, and use fmgr.h value from fmgr.h. 1998-05-13 03:44:24 +00:00
Bruce Momjian
09baa3cc81 This patch...
1. Removes the unnecessary "#define AbcRegProcedure 123"'s from
pg_proc.h.

2. Changes those #defines to use the names already defined in
fmgr.h.

3. Forces the make of fmgr.h in backend/Makefile instead of having
it
   made as a dependency in access/common/Makefile  *hack*hack*hack*

4. Rearranged the #includes to a less helter-skelter arrangement,
also
    changing <file.h> to "file.h" to signify a non-system header.

5. Removed "pg_proc.h" from files where its only purpose was for
the
   #defines removed in item #1.

6. Added "fmgr.h" to each file changed for completeness sake.

Turns out that #6 was not necessary for some files because fmgr.h
was being included in a roundabout way SIX levels deep by the first
include.

"access/genam.h"
 ->"access/relscan.h"
   ->"utils/rel.h"
     ->"access/strat.h"
       ->"access/skey.h"
	 ->"fmgr.h"

So adding fmgr.h really didn't add anything to the compile, hopefully
just made it clearer to the programmer.

1e801a8f16 Hi,
Attached you'll find a (big) patch that fixes make dep and make
depend in all Makefiles where I found it to be appropriate.

It also removes the dependency in Makefile.global for NAMEDATALEN
and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh
a little smarter.

This no longer requires initdb.sh that is turned into initdb with
a sed script when installing Postgres, hence initdb.sh should be
renamed to initdb (after the patch has been applied :-) )

This patch is against the 6.3 sources, as it took a while to
complete.

Please review and apply,

Cheers,

57b5966405 The following uuencoded, gzip'd file will ...
1. Remove the char2, char4, char8 and char16 types from postgresql
2. Change references of char16 to name in the regression tests.
3. Rename the char16.sql regression test to name.sql.  4. Modify
the regression test scripts and outputs to match up.

Might require new regression.{SYSTEM} files...

aa7244ed01 Change:
#define TAPETEMP                "pg_btsortXXXXXX"

to:

#define TAPETEMP                "pg_btsortXXXXXXX"

For some reason, under FreeBSD, it appears that the mktemp() value needs the
extra 'X' to improve/ensure uniqueness

c65ea0e040 New pg_attribute.atttypmod for type-specific information like
varchar length.

Cleans up code so attlen is always length.

Removed varchar() hack added earlier.

Will fix bug in selecting varchar() fields, and varchar() can be
variable length.

baef78d96b Thank god for searchable mail archives.
Patch by: wieck@sapserv.debis.de (Jan Wieck)

   One  of  the design rules of PostgreSQL is extensibility. And
   to follow this rule means (at least for me) that there should
   not  only  be a builtin PL.  Instead I would prefer a defined
   interface for PL implemetations.

374bb5d261 Some *very* major changes by darrenk@insightdist.com (Darren King)
==========================================
What follows is a set of diffs that cleans up the usage of BLCKSZ.

As a side effect, the person compiling the code can change the
value of BLCKSZ _at_their_own_risk_.  By that, I mean that I've
tried it here at 4096 and 16384 with no ill-effects.  A value
of 4096 _shouldn't_ affect much as far as the kernel/file system
goes, but making it bigger than 8192 can have severe consequences
if you don't know what you're doing.  16394 worked for me, _BUT_
when I went to 32768 and did an initdb, the SCSI driver broke and
the partition that I was running under went to hell in a hand
basket. Had to reboot and do a good bit of fsck'ing to fix things up.

The patch can be safely applied though.  Just leave BLCKSZ = 8192
and everything is as before.  It basically only cleans up all of the
references to BLCKSZ in the code.

If this patch is applied, a comment in the config.h file though above
the BLCKSZ define with warning about monkeying around with it would
be a good idea.

Darren  darrenk@insightdist.com

(Also cleans up some of the #includes in files referencing BLCKSZ.)

e2d9501094 Clean up the Makefiles
Essentially, this cleans things up so that if PORTNAME isn't defined (I'm
    working on getting rid of it for FreeBSD, at least, to see if its possible)
    none of the PORTNAME related stuff gets passed around.

	Had a little bit of -I related redundancy as well
