Bruce Momjian	9a0dd4fb18	There's a patch attached to fix gcc 2.8.x warnings, except for the ... yyerror ones from bison. It also includes a few 'enhancements' to the C programming style (which are, of course, personal). The other patch removes the compilation of backend/lib/qsort.c, as qsort() is a standard function in stdlib.h and can be used any where else (and it is). It was only used in backend/optimizer/geqo/geqo_pool.c, backend/optimizer/path/predmig.c, and backend/storage/page/bufpage.c > > Some or all of these changes might not be appropriate for v6.3, since we > > are in beta testing and since they do not affect the current functionality. > > For those cases, how about submitting patches based on the final v6.3 > > release? There's more to come. Please review these patches. I ran the regression tests and they only failed where this was expected (random, geo, etc). Cheers, Jeroen	28 years ago
Bruce Momjian	c579ce0fb0	I started adding the Having Clause and it works quite fine for ... sequential scans! (I think it will also work with hash, index, etc but I did not check it out! I made some High level changes which should work for all access methods, but maybe I'm wrong. Please let me know.) Now it is possible to make queries like: select s.sname, max(p.pid), min(p.pid) from part p, supplier s where s.sid=p.sid group by s.sname having max(pid)=6 and min(pid)=1 or avg(pid)=4; Having does not work yet for queries that contain a subselect statement in the Having clause, I'll try to fix this in the next days. If there are some bugs, please let me know, I'll start to read the mailinglists now! Now here is the patch against the original 6.3 version (no snapshot!!): Stefan	28 years ago

Vadim B. Mikheev	4a6e3a6a9f	Old planner() becomes union_planner(); new planner() makes initialization ... of some global variables to support subselects and calls union_planner(). Calls to SS_replace_correlation_vars() and SS_process_sublinks() in query_planner() before planning. Get rid of #ifdef INDEXSCAN_PATCH in createplan.c.	28 years ago

PostgreSQL Daemon	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.	28 years ago

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. Darren darrenk@insightdist.com (Also cleans up some of the #includes in files referencing BLCKSZ.) ==========================================	28 years ago
Bruce Momjian	679d39b9c8	Goodbye ABORT. Hello ERROR for all errors.	28 years ago
Bruce Momjian	9d00fbbeb0	Change some labels in bootparse to make ctags happy. Clean up outfunc/readfunc code and add missing fields for Query structure and new Union fields. Fix optimizer bug shown in new \do command. Change WARN to ERROR in contrib and regression stuff.	28 years ago

Marc G. Fournier	6e337eef45	Major cleanout of PORTNAME variables from Makefiles...bound to screw up ... some of the ports...	28 years ago
Marc G. Fournier	5379b84eff	More cleanups. I can now compile without PORTNAME being defined n ... 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 :)	28 years ago
