Vadim B. Mikheev	72d271177c	Have to copyObject((void*)clauseinfo) for a relation' joininfo (in add_join_clause_info_to_rels()) : clause may be commutted later.	29 years ago
Vadim B. Mikheev	e349eb6e2c	Bug (yet unfixed but not fatal) found: Re-moving index clauses from the nestloop's join clauses doesn't work in some cases: * 1. fix_indxqual_references may change varattno-s in * inner_indxqual; * 2. clauses may be commuted	29 years ago

Marc G. Fournier	1c688d1bbe	From: "Martin S. Utesch" <utesch@aut.tu-freiberg.de> 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.	29 years ago
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)selecindextuples) as estimation for expected heap pages: ceil((double)selecrelpages) now.	29 years ago
Vadim B. Mikheev	fa2629b7ea	Fix (hack) IndexSelectivity(): 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 ?	29 years ago
Vadim B. Mikheev	d12e27a5f3	Changes for GROUP BY func_results: AddGroupAttrToTlist() is not called from anywhere now.	29 years ago

Marc G. Fournier	c7b40e6058	This commit represents a clean compile with the new templates under FreeBSD The Makefile(s) have all been cleaned up such that there is a single LDFLAGS vs LD_ADD or LDADD or LDFLAGS or LDFLAGS_BE. The Makefile(s) should be alot more straightforward then they were before...and consistent	29 years ago
Marc G. Fournier	9d5c0af586	From: Thomas Lockhart <Thomas.G.Lockhart@jpl.nasa.gov> Subject: [HACKERS] Aggregate function patches Here are the aggregate function patches I originally sent in last December. They fix sum() and avg() behavior for ints and floats when NULL values are involved. I was waiting to resubmit these until I had a chance to write a v6.0->v6.1 database upgrade script to ensure that existing v6.0 databases which have not been reloaded for v6.1 do no break with the new aggregate behavior. These scripts are included below. It's OK with me if someone wants to do something different with the upgrade strategy, but something like this was discussed a few weeks ago. Also, there were a couple of small items which cropped up in doing a clean install of 970403 (actually 970402 + 970403 changes since the full 970403 tar file appears to be damaged or at least suspect). They are the first two patches below and can be omitted if desired (although I think they aren't dangerous :).	29 years ago
Marc G. Fournier	5b1311acfb	From: Oleg Bartunov <oleg@sai.msu.su> Subject: [HACKERS] locale patches ! Hi there, here are little patches to get Postgres 6.1 works with locale stuff. This is a patch against 970402.tar.gz, there are no problem to apply them by hand to 6.0 release. Collate stuff tested about 1-2 months in real working database but I'm sure there must be no problem. US hackers could vote against locale implementation ( locale for sure will affect to speed of postgres ), so I introduce variable USE_LOCALE which controls locale stuff. Non-US users now could use ~* operator for searching and <order by> for strings with nation alphabet. Please, don't forget, as I did first time, to set environment variable LC_CTYPE and LC_COLLATE because backend get locale information from them. I start postmaster from a little script, assuming that shell is Bash shell it looks like: #!/bin/sh export LC_CTYPE=koi8-r export LC_COLLATE=koi8-r postmaster -B 1024 -S -D/usr/local/pgsql/data/ -o '-Fe'	29 years ago

Marc G. Fournier	5dde558ce6	From: Dan McGuirk <mcguirk@indirect.com> Subject: [HACKERS] linux/alpha patches These patches lay the groundwork for a Linux/Alpha port. The port doesn't actually work unless you tweak the linker to put all the pointers in the first 32 bits of the address space, but it's at least a start. It implements the test-and-set instruction in Alpha assembly, and also fixes a lot of pointer-to-integer conversions, which is probably good anyway.	29 years ago

Vadim B. Mikheev	fb24bfa3ce	INDEXSCAN_PATCH changes: should work for (Param OP VAR) too (but I didn't test FUNC OP PARAM and PARAM OP FUNC - no time)	29 years ago
Vadim B. Mikheev	1aa1827d64	1. INDEXSCAN_PATCH changes: (op Param Var) should work too 2. IndexScanableOperand now uses match_indexkey_operand instead of equal_indexkey_var (if we have some index on attribute X then we shouldn't use it for 'where some_func(X) OP CONST').	29 years ago
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...
