Tom Lane 7a7ba33536 Clean up some bogosities in path cost estimation, like 
sometimes estimating an index scan of a table to be cheaper than a
sequential scan of the same tuples...

Tom Lane e91f43a122 Fix potential overflow problems when relation size exceeds 
2gig.  Fix failure to reliably put the smaller relation on the inside of
a hashjoin.

Marc G. Fournier 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.

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

Bruce Momjian 319dbfa736 Another PGINDENT run that changes variable indenting and case label indenting. Also static variable indenting. 1997-09-08 02:41:22 +00:00
Bruce Momjian 1ccd423235 Massive commit to run PGINDENT on all *.c and *.h files. 1997-09-07 05:04:48 +00:00
Bruce Momjian 1d8bbfd2e7 Make functions static where possible, enclose unused functions in #ifdef NOT_USED. 1997-08-19 21:40:56 +00:00
Vadim B. Mikheev 4ec8a148ed Add innercost to result in cost_hashjoin. 1997-04-24 15:49:30 +00:00
Vadim B. Mikheev 610d0d00ed 1. Enable to have different _CPU_PAGE_WEIGHT_ for heap and index. 
2. PageWeights are variables now.
3. Fixed using ceil((double)selec*indextuples) as estimation
for expected heap pages: ceil((double)selec*relpages) now.

Marc G. Fournier d90a426e35 Linux defines MAXINT in values.h, which causes an error when compiling.

 1997-01-26 16:06:42 +00:00
Marc G. Fournier 3ffd5694dd Replace occurances of USE_{LIMITS,VALUES}_H with HAVE_* in preparation 
for switch over to configure
 1997-01-24 18:00:48 +00:00
Marc G. Fournier f504e5a253 Taking a chance here. Under both Solaris and FreeBSD, there is a 
/usr/include/limits.h (which quiets the costsize.c warnings)...under
FreeBSD, /usr/include/limits.h *includes* machine/limits.h, while under
Solaris, there is no such things as /usr/include/machine...

Problem with Solaris pointed out by Mark Wahl
