Bruce Momjian	513e85a877	Update TODO list.	26 years ago
Tom Lane	1cffbfcb56	Arrange to free planning memory (or most of it, anyway) at completion ... of planning. This should reduce memory requirements for large joins.	26 years ago
Tom Lane	c7793a731c	Ensure that values stored within arrays are not toasted, per ... discussion on pghackers a few days ago.	26 years ago
Bruce Momjian	18f138263b	Update TODO list.	26 years ago
Tom Lane	90451fe7f3	When dealing with OR-of-ANDs quals, extract multiple subclauses of an AND ... to use with a multiple-key index. Formerly we would only extract clauses that had to do with the first key of the index, which was correct but didn't exploit the index fully.	26 years ago

Bruce Momjian	4108bf6def	Update FAQ.	26 years ago
Tom Lane	0e06e68387	ExecRestrPos() really needs to raise ERROR, not a wimpy DEBUG message, ... if given a node type it doesn't support. As is, wrong results from a mergejoin would go undetected.	26 years ago
Tom Lane	742cd87999	Ensure that if the OID counter wraps around, we will not generate 0, ... nor any OID in the reserved range (1-16383).	26 years ago
Tom Lane	667d5ed206	Fix confusion between sizeof(long) and sizeof(long*), as well as ... failure to MAXALIGN the start of shmem allocable space. No reports of trouble here, just compulsive tidiness.	26 years ago
Tom Lane	dc73e25a5e	Add commentary about varying usage of scankeys in btree code.	26 years ago
Tom Lane	916b2321ad	Clean up and document btree code for ordering keys. Neat stuff, ... actually, but who could understand it with no comments? Fix bug while at it: _bt_orderkeys would try to invoke comparisons on NULL inputs, given the right sort of redundant quals.	26 years ago
Tom Lane	da1ad323b7	Update comments.	26 years ago
Bruce Momjian	b9e6f068dc	Update bsdi template	26 years ago
Bruce Momjian	f28ec8c5af	more doc cleanups	26 years ago
Philip Warner	93802c88bb	pg_backup_plain_text.c replaced by pg_backup_null.c	26 years ago
Philip Warner	bb080400f8	- no longer put ACLs at end of dump ... - connect as appropriate user in pg_restore with db connection - dump owner of rule in pg_dump	26 years ago
Tom Lane	cd9f0ca545	Deduce equality constraints that are implied by transitivity of ... mergejoinable qual clauses, and add them to the query quals. For example, WHERE a = b AND b = c will cause us to add AND a = c. This is necessary to ensure that it's safe to use these variables as interchangeable sort keys, which is something 7.0 knows how to do. Should provide a useful improvement in planning ability, too.	26 years ago
Peter Eisentraut	c39c198bc3	Unset locale variables before running regression tests. (All of them!) ... Don't do config.status substitutions into the regression test makefile.	26 years ago
Tom Lane	8d77c1a8aa	Clean up some sloppy casts --- Oid vs. Datum, that sort of thing.	26 years ago
Tom Lane	e4e6459c0f	Further cleanup of array behavior. Slice assignments to arrays with ... varlena elements work now. Allow assignment to previously-nonexistent subscript position to extend array, but only for 1-D arrays and only if adjacent to existing positions (could do more if we had a way to represent nulls in arrays, but I don't want to tackle that now). Arrange for assignment of NULL to an array element in UPDATE to be a no-op, rather than setting the entire array to NULL as it used to. (Throwing an error would be a reasonable alternative, but it's never done that...) Update regress test accordingly.	26 years ago
Peter Eisentraut	ef2a6b8b83	Shed some light onto SysV IPC configuration.	26 years ago
Peter Eisentraut	100dd889d6	typos	26 years ago
Jan Wieck	f67e79045d	2nd try for the index tuple toast hack. This time as suggested ... by Tom. Jan	26 years ago
Tom Lane	a5a12887a1	Make update lists like 'UPDATE tab SET foo[1] = bar, foo[3] = baz' ... work as expected. THe underlying implementation is essentially 'SET foo = array_set(foo, 1, bar)', so we have to turn the items into nested invocations of array_set() to make it work correctly. Side effect: we now complain about 'UPDATE tab SET foo = bar, foo = baz' which is illegal per SQL92 but we didn't detect it before.	26 years ago

Bruce Momjian	4140085adb	spell cleanups	26 years ago
Tom Lane	4bdb348628	Remove 'Array' node type, which has evidently been dead code for ... a very long time.	26 years ago
Tom Lane	1afdccc8b2	Missed some array updates ...	26 years ago
Tom Lane	d0e17e2112	Arrays are toastable. (At least if you initdb, which I didn't force.) ... Remove a bunch of crufty code for large-object-based arrays, which is superseded by TOAST and likely hasn't worked in a long time anyway. Clean up array code a little, and in particular eliminate its habit of scribbling on the input array (ie, modifying the input tuple :-().	26 years ago
Bruce Momjian	ec37ea1cc1	Cleanups	26 years ago
Peter Eisentraut	bb13830d6f	maintainer-clean and distclean ought to remove dependency information as well.	26 years ago
Tom Lane	cf14ccd0ea	Fix typo in version-mismatch error report.	26 years ago
Tom Lane	421f0baaff	Further cleanup of btbuild (CREATE INDEX). Avoid storing unneeded ... left keys during bottom-up index build, and leave some free space instead of packing the pages to the brim (so as to avoid vast numbers of page splits during the first interactive insertions).	26 years ago
Tom Lane	1ea912e16d	Fix sloppiness about alignment requirements in findsplitloc() space ... calculation, also make it stop when it has a 'good enough' split instead of exhaustively trying all split points.	26 years ago
Bruce Momjian	2f011a9c72	More doc cleanups, from book.	26 years ago
Bruce Momjian	c281847fcd	More doc cleanups	26 years ago
Bruce Momjian	c62e961da1	Update for sh.	26 years ago
Philip Warner	c3e18804ff	- Support for TAR output ... - Support for BLOB output from pg_dump and input via pg_restore - Support for direct DB connection in pg_restore - Fixes in support for --insert flag - pg_dump now outputs in modified OID order	26 years ago
Philip Warner	e8f69be054	- Support for BLOB output from pg_dump and input via pg_restore ... - Support for direct DB connection in pg_restore - Fixes in support for --insert flag - pg_dump now outputs in modified OID order - various other bug fixes	26 years ago
Jan Wieck	0143d391c6	Need to switch to tuples memory context when replacing the toasted ... one with the plain one. Jan	26 years ago
Jan Wieck	82f3945a67	Temporary fix to make TOAST vacuum-safe. All values are forced to be ... in memory (plain or compressed) in the tuple returned from the heap-am. So no index will ever contain an external reference. Jan	26 years ago
Tom Lane	9e85183bfc	Major overhaul of btree index code. Eliminate special BTP_CHAIN logic for ... duplicate keys by letting search go to the left rather than right when an equal key is seen at an upper tree level. Fix poor choice of page split point (leading to insertion failures) that was forced by chaining logic. Don't store leftmost key in non-leaf pages, since it's not necessary. Don't create root page until something is first stored in the index, so an unused index is now 8K not 16K. (Doesn't seem to be as easy to get rid of the metadata page, unfortunately.) Massive cleanup of unreadable code, fix poor, obsolete, and just plain wrong documentation and comments. See src/backend/access/nbtree/README for the gory details.	26 years ago
