Bruce Momjian	ca5c10f778	Update TODO list.	26 years ago
Tatsuo Ishii	02efaa14e5	Old multi-byte bug. Forgot to rename #ifdef MB to #ifdef MULTIBYTE Now SET NAMES working again...	26 years ago
Tom Lane	abee4c299f	Remove extraneous SeqScan node that make_noname was inserting above a Sort or Materialize node. As far as I can tell, the only place that actually needed that was set_tlist_references, which was being lazy about checking to see if it had a noname node to fix or not...	26 years ago
Tom Lane	6defe4949e	Add script that runs the regression tests with all valid combinations of query-plan-type backend options. Good for testing planner/optimizer. Tedious, though.	26 years ago
Bruce Momjian	898b21267d	Add missing docs semicolon.	26 years ago
Tom Lane	ed3f69168f	EXPLAIN didn't know about 'Materialize' plan nodes.	26 years ago
Tom Lane	91f82de48a	Assign sort keys properly when there are duplicate entries in pathkey list --- corrects misbehavior seen with multiple mergejoin clauses mentioning same variable.	26 years ago
Bruce Momjian	55179388f9	Typo fix	26 years ago
Bruce Momjian	972124091d	I've sent 3 mails to pgsql-patches. There are two files, one for doc and for src/data directories, and one minor patch for doc/README.locale. Please apply. Oleg.	26 years ago
Bruce Momjian	c5d0a1bc42	Fix for perl5 on BSD/OS.	26 years ago
Bruce Momjian	aa2cc6ebbe	Change >& to > and 2>&1.	26 years ago
Bruce Momjian	e69a997d02	Allow BSD yacc and bison to compile pl code.	26 years ago
Tom Lane	e6381966c1	Major planner/optimizer revision: get rid of PathOrder node type, store all ordering information in pathkeys lists (which are now lists of lists of PathKeyItem nodes, not just lists of lists of vars). This was a big win --- the code is smaller and IMHO more understandable than it was, even though it handles more cases. I believe the node changes will not force an initdb for anyone; planner nodes don't show up in stored rules.	26 years ago
Tom Lane	08320bfb22	Small updates to #include lists for pending optimizer checkin.	26 years ago
Tom Lane	c9b128fcdb	Move funcid_get_rettype() to lsyscache.	26 years ago
Tom Lane	b1baf1ff60	Add get_func_rettype() to general-use lsyscache routines, since it's now needed in both optimizer and parser.	26 years ago
Tatsuo Ishii	bab13a70ff	Fix for Win32 making problem with MB enabled. Patches created by Hiroki Kataoka.	26 years ago
Thomas G. Lockhart	3cfd56fcf6	Repair the check for redundant UNIQUE and PRIMARY KEY indices. Also, improve it so that it checks for multi-column constraints. Thanks to Mark Dalphin <mdalphin@amgen.com> for reporting the problem.	26 years ago
Tom Lane	288373f5a4	LispUnion fix changes output ordering for inheritance tests.	26 years ago
Tom Lane	51e29a2be3	LispUnion routine didn't generate a proper union: anytime l2 contained more than one entry, there would be duplicates in the output list. Miscellaneous code beautification in other routines, too.	26 years ago
Bruce Momjian	448d1ab0ad	Update TODO list.	26 years ago
Tom Lane	47f18ec702	Update comments about pathkeys.	26 years ago
Tom Lane	8f9f6e51a8	Clean up optimizer's handling of indexscan quals that need to be commuted (ie, the index var appears on the right). These are now handled the same way as merge and hash join quals that need to be commuted: the actual reversing of the clause only happens if we actually choose the path and generate a plan from it. Furthermore, the clause is only reversed in the 'indexqual' field of the plan, not in the 'indxqualorig' field. This allows the clause to still be recognized and removed from qpquals of upper level join plans. Also, simplify and generalize match_clause_to_indexkey; now it recognizes binary-compatible indexes for join as well as restriction clauses.	26 years ago
Tom Lane	aae034d28c	Add commentary to show that even though ExecInitIndexScan() contains much code that looks like it will handle indexquals with the index key on either side of the operator, in fact indexquals must have the index key on the left because of limitations of the ScanKey machinery. Perhaps someone will be motivated to fix that someday...	26 years ago
Bruce Momjian	6075717df0	Update TODO list.	26 years ago
Tom Lane	2ae51c86c9	Minor cleanups and code beautification; eliminate some routines that are now dead code.	26 years ago
Tom Lane	4a1c5cb953	Revise create_nestloop_node's handling of inner indexscan to work under a wider range of scenarios than it did --- it formerly did not handle a multi-pass inner scan, nor cases in which the inner scan's indxqualorig or non-index qual contained outer var references. I am not sure that these limitations could be hit in the existing optimizer, but they need to be fixed for future expansion.	26 years ago

Tom Lane	5efe31214a	Clean up tlist.c tree-walking routines with expression_tree_mutator.	26 years ago
Tom Lane	14f84cd821	Store -1 in attdisbursion to signal 'no duplicates in column'. Centralize att_disbursion readout logic.	26 years ago
Tom Lane	5af4b04f31	Move get_attdisbursion to lsyscache. Clean up get_typdefault.	26 years ago
Tom Lane	e9054829a2	Update comments about attdisbursion. NO code change.	26 years ago
Vadim B. Mikheev	1ecb43a40c	Re-use free space on index pages with duplicates.	26 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...	26 years ago
Tom Lane	ecef2caae9	Clean up routines in setrefs.c by replacing individual tree walking logic with expression_tree_walker/mutator calls.	26 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.	26 years ago
Bruce Momjian	f0b651ac6b	replace #Include .	26 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()?	26 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.	26 years ago
Thomas G. Lockhart	a76ad509fe	Remove old man pages. All info is in new man pages or other docs.	26 years ago
Thomas G. Lockhart	d0a1919852	Use sgml/Makefile to generate man sections, so just "make man" there.	26 years ago
Thomas G. Lockhart	7af929cd79	Switch from old man pages to new ones generated from sgml.	26 years ago
Thomas G. Lockhart	13d1a3c06d	Remove emacs properties block from end of file.	26 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.	26 years ago
Bruce Momjian	4cddd482c1	Fix so BSD yacc works on file.	26 years ago
Thomas G. Lockhart	c879556780	Fix markup to allow clean man pages. Add new pages for programming languages and tcl shells.	26 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.	26 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.	26 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 :()	26 years ago
