Subject: [HACKERS] Money integration patches

Here are patches to integrate the money data type. I have included
some math and aggregate functions and have made the locale support optional
by #ifdef USE_LOCALE bracketing of functions.

Modules affected are:
builtins.h.patch
cash.c.patch
cash.h.patch
main.c.patch
pg_aggregate.h.patch
pg_operator.h.patch
pg_proc.h.patch
pg_type.h.patch

I changed the data type to be pass-by-reference rather than by-value
to pave the way for a larger internal representation (64-bit ints?).
Also, I changed the tabbing of cash.c and cash.h to match most of
the other Postgres source code files (4 space indent, 8 spaces == 1 tab).

The locale stuff should be tested under another convention (Russian?)
but I don't know what the correct results should be so perhaps someone
else can give them a try. Will update docs and regression tests in
the next few days.

invalid macro definitions, the compiler complains about:

"pqcomprim.c", line 48.9: 1506-275 (S) Unexpected text ';' ignored.
"pqcomprim.c", line 61.9: 1506-275 (S) Unexpected text ';' ignored.

The ';' terminating the macro definition ntoh_s(n) on line 27 and
ntoh_l(n) on line 28 should be removed.

Change BSD44_derived to __FreeBSD__ in numutils.c (need to know what
NetBSD is referred to as...someone?)

configure ([] have special means to m4 *sigh*)

file that has moved to include is also link'd properly

Makefile.global and move them to seperate 'include' makefiles

Over time, should become even more port specific:

	ie. Makefile.BSD44_derived should be broken down into netbsd/freebsd
specific ports

Moved to include/port

modification to c.h so that bool isn't typedef'd under __cplusplus

testing

Remove the TEST_MAIN stuff at the top...

	- if someone can pick a better \? for this, plesae let me know...all
	  the good ones seem taken :(

Submitted by: adrian@waltham.harvard.net

but it gets rid of the temptation to modify the old source files :)

pg_proc.h still needs modifying, but this gets it in there so that we can
get around any compiler bugs.  Will try and get the pg_proc.h entries done
up later tonight...

Subject: Re: [HACKERS] GEQO and views (rules)


Oke, this was caused by a classic bug :-/
I thougth, root->base_relation_list_ could be
represented as relid string 1-2-3-4- etc.

Instead, in case of views, the count of relids doesn't start with "1" but
maybe 4-5-6- etc . :-(

GEQO patch follows ... views are now all right.

varlena.c - part of Thomas' most recent patch

weighting factor */) in addition to
#define _CPU_PAGE_WEIGHT_  0.065 (/* CPU-heap-to-page cost weighting factor
*/).

ATTNVALS_SCALE/reltuples (instead of reltuples).

2. PageWeights are variables now.
3. Fixed using ceil((double)selec*indextuples) as estimation
for expected heap pages: ceil((double)selec*relpages) now.

use sum(npages)/((nkeys == 1) ? 1 : nkeys + 1) as expected index page
estimation for multi-key quals - instead of sum(npages).
In old code npages for x > 10 and x < 20 is twice as for x > 10 - cool ?

regress.sh modified to get rid of queries.sql tests, as they are
performed vis sql/*.sql

Its starting to actually take shape and look as expected...

should be used :)

partially split

The whole file needs updating, but will work on that after finishing
with the splits
