Tom Lane	39cd6e2e91	outfuncs.c was missing a print routine for Material plan nodes, leading to trouble when trying to EXPLAIN VERBOSE a plan containing one.	26 years ago
Tom Lane	eca02fee2c	Rename bytea functions to not have upper-case letters in their names. Clean up grotty coding in them, too. AFAICS from the CVS logs, these have been broken since Postgres95, so I'm not going to insist on an initdb to fix them now...	26 years ago
Tom Lane	0edcee3459	Fold PQsetenv working state into PGconn, rather than trying to maintain it in a separate object. There's no value in keeping the state separate, and it creates dangling-pointer problems. Also, remove PQsetenv routines from public API, until and unless they are redesigned to have a safer interface. Since they were never part of the documented API before 7.0, it's unlikely that anyone is calling them.	26 years ago
Tatsuo Ishii	5b1f92eaa7	Update multi-byte support README	26 years ago
Bruce Momjian	853cf66176	Update HISTORY	26 years ago
Tom Lane	7177bbac29	A little further tweaking of the range-query selectivity logic: to avoid undue sensitivity to roundoff error, believe that a zero or slightly negative range estimate should represent a small positive selectivity, rather than falling back on a generic default estimate.	26 years ago
Bruce Momjian	6d79d6027c	>> 5. empty define that results in an empty but terminated line ( ; ) easy (maybe dumb) fix for 5 in attachment define.patch greetings, Andreas	26 years ago
Bruce Momjian	f8645018bc	Back out // compiler flag.	26 years ago
Bruce Momjian	4ddc50dffa	Hmm, absolute pathnames for the copy makes sense. I'll whip up that patch in a second. Should be sufficent to just make sure the first character is a '/', right? Ross J. Reedstrom	26 years ago
Bruce Momjian	b2d867fb08	Some points for portability improvements: 1. C++ style comments in C source for ecpg ( // comment ) 2. compiler finds wrong include file extern.h in ecpg/lib/descriptor.c from include path instead of workdir (rename it ?) 3. fe-connect getsockopt takes a socklen_t as fifth arg not int (use SOCKET_SIZE_TYPE instead) 4. char vs unsigned char in psql calls to libpq 5. empty define that results in an empty but terminated line ( ; ) Now for all but point 3 I can supply changes to the compiler flags, to make the compiler less pedantic. Or is someone interested in the complications ? in the meantime can someone apply the attached patch ? Andreas	26 years ago
Bruce Momjian	90cb4c89df	Update history/sgml.	26 years ago
Bruce Momjian	2f839c58e2	Please apply the attached patch to interfaces/libpq/libpq-fe.h. This would allow to write applications which do not have a link to postgres_ext.h in their source directory. Andreas Kardos	26 years ago
Michael Meskes	ac3884e2a9	* empty log message *	26 years ago
Tom Lane	3097788f66	subselect regress test was kind of silly; it claimed to test correlation cases but actually did no such thing. Make it test some more cases than before (including things that didn't work in 6.5).	26 years ago
Tom Lane	5c63975504	Float-to-int conversion functions should return NULL when given NULL input, not throw a gratuitous elog().	26 years ago
Tom Lane	37ab088770	Remove no-longer-necessary restriction against uplevel correlation vars outside WHERE clause. Fix a couple of places that didn't handle uplevel refs cleanly.	26 years ago
Tom Lane	dadb14fa60	Hack parse_coerce so it won't try to constant-fold the dummy Const nodes introduced by make_subplan(). It'd be better if we used a different node type for subplan result placeholders, but for now...	26 years ago
Tom Lane	9da6d2c0e7	ExecSubPlan needs to be able to cope with RelabelType nodes atop the Const placeholder nodes for subplan result values.	26 years ago
Bruce Momjian	b212e7ad7b	Update TODO list.	26 years ago
Bruce Momjian	b508136d81	Update HISTORY file for 7.0.	26 years ago
Tatsuo Ishii	5ca8eb9216	Prepare for 7.0 release	26 years ago
Tom Lane	1afaa2557a	If we cannot get a real estimate for the selectivity of a range query, use a default value that's fairly small. We were generating a result of about 0.1, but I think 0.01 is probably better --- want to encourage use of an indexscan in this situation.	26 years ago
Tom Lane	cad764f349	Improve selectivity estimation involving string constants: pay attention to more than one character, and try to do the right thing in non-ASCII locales.	26 years ago
Tom Lane	1d5e7a6f46	Repair logic flaw in cost estimator: cost_nestloop() was estimating CPU costs using the inner path's parent->rows count as the number of tuples processed per inner scan iteration. This is wrong when we are using an inner indexscan with indexquals based on join clauses, because the rows count in a Relation node reflects the selectivity of the restriction clauses for that rel only. Upshot was that if join clause was very selective, we'd drastically overestimate the true cost of the join. Fix is to calculate correct output-rows estimate for an inner indexscan when the IndexPath node is created and save it in the path node. Change of path node doesn't require initdb, since path nodes don't appear in saved rules.	26 years ago
Bruce Momjian	d825e55c13	Update pg_dumpall again.	26 years ago
Bruce Momjian	233a52eaff	Fix pg_dumpall for new psql output.	26 years ago
Tom Lane	e1a1f22f13	Forgot that odbc had its own copies of config.sub/config.guess. Update those to latest Autoconf sources, too.	26 years ago
Thomas G. Lockhart	b688f8f034	Fix query for primary keys to reflect new DISTINCT ON () syntax. Reported by "Tibor Laszlo" <ltibor@mail.tiszanet.hu> and fix suggested by "Hiroshi Inoue" <Inoue@tpf.co.jp>.	26 years ago
Thomas G. Lockhart	dcdcada7e9	Add syntax for BIT() and BIT VARYING(), but no underlying implementation is available yet. Remove redundant call to xlateSqlType() in the character type handling code.	26 years ago
Thomas G. Lockhart	3c7ca8d459	Update test for new ORDER BY clause from Tom Lane.	26 years ago
Tom Lane	3ee8f7e207	Restructure planning code so that preprocessing of targetlist and quals to simplify constant expressions and expand SubLink nodes into SubPlans is done in a separate routine subquery_planner() that calls union_planner(). We formerly did most of this work in query_planner(), but that's the wrong place because it may never see the real targetlist. Splitting union_planner into two routines also allows us to avoid redundant work when union_planner is invoked recursively for UNION and inheritance cases. Upshot is that it is now possible to do something like select float8(count()) / (select count() from int4_tbl) from int4_tbl group by f1; which has never worked before.	26 years ago
Tom Lane	aafe86d995	Correct typo in error message.	26 years ago
Bruce Momjian	1d5df1547a	This patch corrects spelling, grammar and euphony for the psql reference page for 7.0: Oliver Elphick	26 years ago
Bruce Momjian	2216584bcf	Reverse out BYTEA type coersion.	26 years ago
Vadim B. Mikheev	df238b2c06	Turn XLOG off (do not create log file).	26 years ago
Tom Lane	3caa56fe5e	Emit 'this operator is deprecated' warnings for ':' and ';'.	26 years ago
Tom Lane	72b4086711	Convert float8 regress test to use exp() and ln() instead of ':' and ';' operators.	26 years ago
Bruce Momjian	7f116a6b83	Update for BYTEAOID.	26 years ago
Tom Lane	8fc97e8276	Sorry, I have read the misspelling 'coersion' one time too many.	26 years ago
Tom Lane	b9a990d8a8	Add exp(), ln(), and some other functions to numeric-functions table.	26 years ago
Tom Lane	339fe3c4cb	Add note that ':' and ';' operators are deprecated.	26 years ago
Bruce Momjian	0e1f485f5f	Add compatiblity information for bytea.	26 years ago
Hiroshi Inoue	fe8098ed0c	Add FORCE keyword to ColID	26 years ago
Tom Lane	966b5337e9	Make use of pre-existing regexp match capability to eliminate redundant entries in template selection rules. Also, change alpha-dec-osf pattern to cope with version info attached to the 'alpha' part.	26 years ago
Tom Lane	42ef928327	Autoconf run	26 years ago
Tom Lane	641c368ae9	Change configure.in to note that since we are using expr(1)'s regex match command, the entries in template/.similar can really be regular expressions. This isn't a new feature, just an observation of what the code already did.	26 years ago
Tom Lane	b178865891	cash_words_out function truncated its output by 1 character due to incorrect use of StrNCpy.	26 years ago
Tom Lane	58422dd0af	Several calls to StrNCpy incorrectly subtracted 1 from the length arg, leading to postmaster accepting args 1 shorter than it had room for.	26 years ago
Tom Lane	6a02746550	Change MemSet and StrNCpy to evaluate their arguments only once. Fix inadequate parenthesization in several other macros.	26 years ago
Tom Lane	fdd7f59820	Since PORTNAME is no longer used at the level of C code (it's only in Makefiles now), there's no reason for os2client to maintain its own copy of c.h just to change #define PORTNAME. Simplify Makefile accordingly. Get rid of horribly-out-of-date modified copy of c.h, which should never have been in the distribution to start with, since it's actually a derived file. Now it's not needed anyway.	26 years ago
