Tom Lane	e9054829a2	Update comments about attdisbursion. NO code change.	27 years ago
Vadim B. Mikheev	1ecb43a40c	Re-use free space on index pages with duplicates.	27 years ago
Tom Lane	10d6d411a8	Rewrite fix_indxqual_references, which was entirely bogus for ... multi-scan indexscan plans; it tried to use the same table-to-index attribute mapping for all the scans, even if they used different indexes. It would klugily work as long as OR indexquals never used multikey indexes, but that's not likely to hold up much longer...	27 years ago
Tom Lane	ecef2caae9	Clean up routines in setrefs.c by replacing individual tree ... walking logic with expression_tree_walker/mutator calls.	27 years ago
Tom Lane	6bc601b648	Create a standardized expression_tree_mutator support routine ... to go along with expression_tree_walker. (_walker is not suitable for routines that need to alter the tree structure significantly.) Other minor cleanups in clauses.c.	27 years ago
Bruce Momjian	f0b651ac6b	replace #Include .	27 years ago
Tom Lane	4488b69b4c	Fix nbtree's failure to clear BTScans list during xact abort. ... Also, move responsibility for calling vc_abort into main xact.c list of things-to-call-at-abort. What in the world was it doing down inside of TransactionIdAbort()?	27 years ago
Tom Lane	fb491a5854	For a unique-key attribute (no duplicate values), vacuum analyze ... was recording a disbursion of 0, not the correct value 1/numberOfRows.	27 years ago
Thomas G. Lockhart	a76ad509fe	Remove old man pages. All info is in new man pages or other docs.	27 years ago
Thomas G. Lockhart	d0a1919852	Use sgml/Makefile to generate man sections, so just "make man" there.	27 years ago
Thomas G. Lockhart	7af929cd79	Switch from old man pages to new ones generated from sgml.	27 years ago
Thomas G. Lockhart	13d1a3c06d	Remove emacs properties block from end of file.	27 years ago
Thomas G. Lockhart	c9ff1a5a75	Update references to char2 type by using char(2). ... Thanks to Garr Updegraff <garru@uci.edu> for the tip.	27 years ago
Thomas G. Lockhart	f11bdb9db5	Allow nsgmls to validate input by defining the document type. ... Use refentry.sgml as a generic header for man pages through nsgmls.	27 years ago
Bruce Momjian	4cddd482c1	Fix so BSD yacc works on file.	27 years ago
Thomas G. Lockhart	c879556780	Fix markup to allow clean man pages. ... Add new pages for programming languages and tcl shells.	27 years ago
Thomas G. Lockhart	6b07527721	Fix cross-reference markup so that only the *title* of the Operators ... chapter is included, not the chapter itself. Thanks to Evelyn Mitchell <efm@tummy.com> for pointing it out.	27 years ago
Thomas G. Lockhart	777a4f71f0	Remove explicit references to ref/ path in file names; use vpath instead. ... Fix rules for man pages to ensure double-pass to get cross references. Add a few new man pages.	27 years ago
Thomas G. Lockhart	4f1766f1ea	Try to clarify characteristics of the SERIAL type. ... Fix source indenting, which does not affect output. Note: still need docs on NUMERIC and DECIMAL (and let's not talk about regression tests :()	27 years ago
Tom Lane	e1fad50a5d	Revise generation of hashjoin paths: generate one path per ... hashjoinable clause, not one path for a randomly-chosen element of each set of clauses with the same join operator. That is, if you wrote SELECT ... WHERE t1.f1 = t2.f2 and t1.f3 = t2.f4, and both '=' ops were the same opcode (say, all four fields are int4), then the system would either consider hashing on f1=f2 or on f3=f4, but it would *not* consider both possibilities. Boo hiss. Also, revise estimation of hashjoin costs to include a penalty when the inner join var has a high disbursion --- ie, the most common value is pretty common. This tends to lead to badly skewed hash bucket occupancy and way more comparisons than you'd expect on average. I imagine that the cost calculation still needs tweaking, but at least it generates a more reasonable plan than before on George Young's example.	27 years ago
Tom Lane	b7883d7e3a	parse_coerce fix allows early simplification of one ... constant-coercion expression in the rules test.	27 years ago
Tom Lane	fd19a350ea	Revise parse_coerce() to handle coercion of int and float ... constants, not only string constants, at parse time. Get rid of parser_typecast2(), which is bogus and redundant...	27 years ago
Bruce Momjian	5a76a94e41	Update TODO list.	27 years ago
Tom Lane	b15a7c9fbe	Fix ELF test so it doesn't spit up on all non-ELF systems... ... use Autoconf-approved method of testing for predefined symbols, and move it down to where we know what compiler to run and how to run it.	27 years ago
Tom Lane	b0984e6995	Add a VACUUM command in hopes of making pg_upgrade usable again ... in MVCC environment. I do not trust this until Vadim says it's OK...	27 years ago
Michael Meskes	b2a2be4c5a	*** empty log message ***	27 years ago
Tom Lane	8624ff7612	Further selectivity-estimation work. Speed up eqsel() ... (it should just call the given operator, not look up an = operator). Fix intltsel() so that all numeric data types are converted to double before trying to estimate where the given comparison value is in the known range of column values. intltsel() still needs work, or replacement, for non-numeric data types ... but for nonintegral numeric types it should now be delivering reasonable estimates.	27 years ago

Bruce Momjian	b2a0a4e8f5	I didn't see any further discussion so here is, I hope, a clean fix to ... configure.in to determine if a system is ELF or not. Note that some of the tests earlier may be redundant but I took the safest route. D'Arcy J.M. Cain	27 years ago
Bruce Momjian	aa1bbed7da	Update NT readme.	27 years ago
Tom Lane	44878506d8	First step in fixing selectivity-estimation code. eqsel and ... neqsel now behave as per my suggestions in pghackers a few days ago. selectivity for < > <= >= should work OK for integral types as well, but still need work for nonintegral types. Since these routines have never actually executed before :-(, this may result in some significant changes in the optimizer's choices of execution plans. Let me know if you see any serious misbehavior. CAUTION: THESE CHANGES REQUIRE INITDB. pg_statistic table has changed.	27 years ago
Tom Lane	f851c6b07d	Add another ORDER BY to rules test; got tired of it 'failing' ... every time I tweak the optimizer...	27 years ago
Tom Lane	970ef45c41	Re-enable pg_upgrade, after adding checks that the source ... and target databases are of versions it knows about.	27 years ago

Tom Lane	04578a9180	Further cleanups of indexqual processing: simplify control ... logic in indxpath.c, avoid generation of redundant indexscan paths for the same relation and index.	27 years ago

Tom Lane	7d572886d6	Fix coredump seen when doing mergejoin between indexed tables, ... for example in the regression test database, try select * from tenk1 t1, tenk1 t2 where t1.unique1 = t2.unique2; 6.5 has this same bug ...	27 years ago
