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.
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.
Pass List* of Aggregs into executor, and create needed array there.
No longer need to double-processs Aggregs with second copy in Query.
Fix crash when doing:
select sum(x+1) from test where 1 > 0;
==========================================
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.)
==========================================
Makefile.global.
End result, if all goes well, should allow for much easier porting, since
there will no longer be a concept of a "port". Most, if not everything,
*should* be determined by configure, or by the compiler itself. Still
work to be done though :)
Subject: [PORTS] Patches for Irix 6.4
I have worked out how to compile PostgreSQL on Irix 6.4 using the -n32 compiler
mode and version 7.1 of the C compiler. (The n32 compiler use 32 bits
addressing,
but allows access to all the instructions in the MIPS4 instruction set.)
There were several problems:
1) The ld command is not referenced as a macro in all the Makefiles. On
this platform, you have to include -n32 on all the ld commands. Makefiles
were changed as needed.
3) Lots of warnings are generated from the compiler. Since the regression
tests worked OK, I didn't attempt to fix them. If anyone wants the compilation
log, please let me know, and I'll email it to you.
The version of postgresql was 970602. Here is Makefile.custom:
CUSTOM_COPT = -O2 -n32
MK_NO_LORDER = 1
LD = ld -n32
CC += -n32
