Bruce Momjian	bc0595f27f	Update TODO list.	27 years ago
Tom Lane	a55888ec9c	Fix nodeAgg coredump in case where lower-level plan has ... an empty targetlist *and* fails to return any tuples, as will happen for example with 'SELECT COUNT(1) FROM table WHERE ...' if the where- clause selects no tuples. It's so nice to make a fix by diking out code, instead of adding more...	27 years ago

Bruce Momjian	341e360d67	Sorry, guys. Here is the ultimate patch which keeps the entire ... behavior as it was, apart from forbidding minus-terminated operators. Seems that I have to break the habit of doing before thinking properly :-/ The point is that my second patch breaks constructs like a & b or a ! b. This patch is to be applied instead of any of two other today's patches. Leon	27 years ago

Bruce Momjian	7d7fb02148	Following advice from Michael Ansley, I broke up the patch in ... two: one fixes uminus and other literal length. They are to be applied - uminus first, then possilbly literal on top of uminus. Leon	27 years ago
Bruce Momjian	3f5a164387	Hello, ... Two patches included: - the first one enables the use of bool variables in fields which might become NULL. Up to now the lib told you that NULL is not a bool variable, even if you provide a indicator. - the second patch checks whether a value is null and issues an error if no indicator is provided. Sidenote: IIRC, the variable should be left alone if the value is NULL. ECPGlib sets it's value to 0 on NULL. Is this a violation of the standard? Regards Christof	27 years ago

Bruce Momjian	7b2a8e4e56	Currently,only the first column of multi-column indices ... is used to find start scan position of Indexscan-s. To speed up finding scan start position,I have changed _bt_first() to use as many keys as possible. I'll attach the patch here. Regards. Hiroshi Inoue	27 years ago

Bruce Momjian	e0e7daef6d	Lots of patches coming in from me today :-) ... When drawing up a very simple "text-drawing" of how the negotiation is done, I realised I had done this last part (fallback) in a very stupid way. Patch #4 fixes this, and does it in a much better way. Included is also the simple text-drawing of how the negotiation is done. //Magnus	27 years ago
Bruce Momjian	3114f92122	Add bsdi sparc port.	27 years ago
Tom Lane	be09bc9ff2	Modify nodeAgg.c so that no rows are returned for a GROUP BY ... with no input rows, per pghackers discussions around 7/22/99. Clean up a bunch of ugly coding while at it; remove redundant re-lookup of aggregate info at start of each new GROUP. Arrange to pfree intermediate values when they are pass-by-ref types, so that aggregates on pass-by-ref types no longer eat memory. This takes care of a couple of TODO items...	27 years ago
Tom Lane	40f6524161	Implement constant-expression simplification per Bernard ... Frankpitt, plus some improvements from yours truly. The simplifier depends on the proiscachable field of pg_proc to tell it whether a function is safe to pre-evaluate --- things like nextval() are not, for example. Update pg_proc.h to contain reasonable cacheability information; as of 6.5.* hardly any functions were marked cacheable. I may have erred too far in the other direction; see recent mail to pghackers for more info. This update does not force an initdb, exactly, but you won't see much benefit from the simplifier until you do one.	27 years ago

Tom Lane	e812458b27	Several changes here, not very related but touching some of the same files. ... * Buffer refcount cleanup (per my "progress report" to pghackers, 9/22). * Add links to backend PROC structs to sinval's array of per-backend info, and use these links for routines that need to check the state of all backends (rather than the slow, complicated search of the ShmemIndex hashtable that was used before). Add databaseOID to PROC structs. * Use this to implement an interlock that prevents DESTROY DATABASE of a database containing running backends. (It's a little tricky to prevent a concurrently-starting backend from getting in there, since the new backend is not able to lock anything at the time it tries to look up its database in pg_database. My solution is to recheck that the DB is OK at the end of InitPostgres. It may not be a 100% solution, but it's a lot better than no interlock at all...) * In ALTER TABLE RENAME, flush buffers for the relation before doing the rename of the physical files, to ensure we don't get failures later from mdblindwrt(). * Update TRUNCATE patch so that it actually compiles against current sources :-(. You should do "make clean all" after pulling these changes.	27 years ago

Bruce Momjian	f66393514f	One last missing quoting bug in pg_dump: ... now that sequence names are properly quoted for field defaults, mixed case sequence names are generated. These are properly quoted in the CREATE SEQUENCE lines, but not in the SELECT nextval lines, as per below: CREATE SEQUENCE "Teams_TeamID_seq" start 10 increment 1 maxvalue 2147483647 minvalue 1 cache 1 ; SELECT nextval ('Teams_TeamID_seq'); This needs to be: SELECT nextval ('"Teams_TeamID_seq"'); Patch included below. -- Ross J.
