indexes.
1. Index Scan using plural indexids never scan backward
as to the order of indexids.
2. The cursor using Index scan is not usable after moving
past the end.
This patch solves above bugs.
Moreover the change of _bt_first() would be useful to extend
ORDER BY patch by Jan Wieck for all descending order cases.

2. Much faster btree tuples deletion in the case when first on page
index tuple is deleted (no movement to the left page(s)).
3. Remember blkno of new root page in BTPageOpaque of
left/right siblings when root page is splitted.
I would like some feedback on what the hash function for the int8 hash
function
in the ./backend/access/hash/hashfunc.c should return.
Also, could someone (maybe Tomas Lockhart?) look-over the patch and make
sure
the system table entries are correct? I've tried to research them as
much as I
could, but some of them are still not clear to me.
Thanks,

Ok. I made patches replacing all of "#if FALSE" or "#if 0" to "#ifdef
NOT_USED" for current. I have tested these patches in that the
postgres binaries are identical.

no longer returns buffer pointer, can be gotten from scan;
descriptor; bootstrap can create multi-key indexes;
pg_procname index now is multi-key index; oidint2, oidint4, oidname
are gone (must be removed from regression tests); use System Cache
rather than sequential scan in many places; heap_modifytuple no
longer takes buffer parameter; remove unused buffer parameter in
a few other functions; oid8 is not index-able; remove some use of
single-character variable names; cleanup Buffer variables usage
and scan descriptor looping; cleaned up allocation and freeing of
tuples; 18k lines of diff;
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.
S Darren.
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,

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...

#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

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.
==========================================
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.

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