Tom Lane	ecbfafbe0e	Add support for Case exprs to fix_indxqual_references, ... so that Case works in WHERE join clauses. Temporary patch --- this routine is one of many that ought to be changed to use centralized expression-tree- walking logic.	27 years ago
Tom Lane	6b157f376a	Add equal() funcs for Case nodes ... amazing we had not ... detected this omission before. Miscellaneous other cleanups.	27 years ago
Bruce Momjian	a06fd1f316	Update TODO list.	27 years ago
Bruce Momjian	8bc25734a1	Update TODO list.	27 years ago
Tom Lane	9682e8081b	Allow a_expr not just AexprConst in the right-hand list of ... IN and NOT IN operators. Rewrite grotty implementation of IN-list parsing ... look Ma, no global variable ...	27 years ago
Bruce Momjian	bb68f6eaa6	Update TODO list.	27 years ago
Tom Lane	b62fdc13f0	Correct bug in best_innerjoin(): it should check all the ... rels that the inner path needs to join to, but it was only checking for the first one. Failure could only have been observed with an OR-clause that mentions 3 or more tables, and then only if the bogus path was actually selected as cheapest ...	27 years ago
Tom Lane	2f30d5a34a	My recent optimizer changes caused a different plan to ... be picked for one of the complex joins in rules test ... leading to a different output ordering ...	27 years ago
Tom Lane	9e7e29e6c9	First cut at doing LIKE/regex indexing optimization in ... optimizer rather than parser. This has many advantages, such as not getting fooled by chance uses of operator names ~ and ~~ (the operators are identified by OID now), and not creating useless comparison operations in contexts where the comparisons will not actually be used as indexquals. The new code also recognizes exact-match LIKE and regex patterns, and produces an = indexqual instead of >= and <=. This change does NOT fix the problem with non-ASCII locales: the code still doesn't know how to generate an upper bound indexqual for non-ASCII collation order. But it's no worse than before, just the same deficiency in a different place... Also, dike out loc_restrictinfo fields in Plan nodes. These were doing nothing useful in the absence of 'expensive functions' optimization, and they took a considerable amount of processing to fill in.	27 years ago

Bruce Momjian	32a505e897	Update TODO list.	27 years ago
Tom Lane	49ed4dd779	Further work on planning of indexscans. Cleaned up interfaces ... to index_selectivity so that it can be handed an indexqual clause list rather than a bunch of assorted derivative data.	27 years ago
Tom Lane	8ae29a1d40	Remove 'restrictinfojoinid' field from RestrictInfo nodes. ... The only place it was being used was as temporary storage in indxpath.c, and the logic was wrong: the same restrictinfo node could get chosen to carry the info for two different joins. Right fix is to return a second list of unjoined-relids parallel to the list of clause groups.	27 years ago
Tom Lane	ac4913a0dd	Clean up messy clause-selectivity code in clausesel.c; repair bug ... identified by Hiroshi (incorrect cost attributed to OR clauses after multiple passes through set_rest_selec()). I think the code was trying to allow selectivities of OR subclauses to be passed in from outside, but noplace was actually passing any useful data, and set_rest_selec() was passing wrong data. Restructure representation of "indexqual" in IndexPath nodes so that it is the same as for indxqual in completed IndexScan nodes: namely, a toplevel list with an entry for each pass of the index scan, having sublists that are implicitly-ANDed index qual conditions for that pass. You don't want to know what the old representation was :-( Improve documentation of OR-clause indexscan functions. Remove useless 'notclause' field from RestrictInfo nodes. (This might force an initdb for anyone who has stored rules containing RestrictInfos, but I do not think that RestrictInfo ever appears in completed plans.)	27 years ago
Tom Lane	348bdbce79	Minor code beautification, extensive improvement of ... comments. This file was full of obsolete and just plain wrong commentary...	27 years ago
Tom Lane	baac6f981e	Exit cleanups I made yesterday caused pq_close() to be ... invoked during exit from a standalone backend, leading to core dump. This is the cause of the recently reported initdb-time crash :-(. Sorry folks...	27 years ago
Bruce Momjian	66f66343f6	Alpha spinlock fix from Uncle George <gatgul@voicenet.com>	27 years ago
Thomas G. Lockhart	f2f43efbe1	Complete merge of all old man page information. ... lisp.sgml is a placeholder for Eric Marsden's upcoming contribution. catalogs.sgml is not yet marked up or integrated. It should perhaps become an appendix.	27 years ago
Thomas G. Lockhart	a27512e634	Complete merge of all old man page information. ... ecpg reference page still needs formatting.	27 years ago

Bruce Momjian	f96babac12	While I was running some tests in psql, trying to figure out how to change ... the query string to handle any length, I discovered that under certain conditions, psql will core dump when handling long strings. Thus, the patch. It was caused by a buffer overrun, probably not noticeable in a lot of cases, but pretty noticeable in mine. Problem was caused by the fact that the length check is only performed after the check for a ; to get the end of the query and execute. Cheers... MikeA	27 years ago

Tom Lane	0c4929ff86	Parser no longer considers ... SELECT a/2, a/2 FROM test_missing_target GROUP BY a/2; to be ambiguous ... which I think is correct behavior.	27 years ago
Tom Lane	7f76eab140	Rewrite parser's handling of INSERT ... SELECT so that processing ... of the SELECT part of the statement is just like a plain SELECT. All INSERT-specific processing happens after the SELECT parsing is done. This eliminates many problems, e.g. INSERT ... SELECT ... GROUP BY using the wrong column labels. Ensure that DEFAULT clauses are coerced to the target column type, whether or not stored clause produces the right type. Substantial cleanup of parser's array support.	27 years ago
