Tom Lane	1663f33838	Tweak btree page split logic so that when splitting a page that is rightmost on its tree level, we split 2/3 to the left and 1/3 to the new right page, rather than the even split we use elsewhere. The idea is that when faced with a steadily increasing series of inserted keys (such as sequence or timestamp values), we'll end up with a btree that's about 2/3ds full not 1/2 full, which is much closer to the desired steady-state load for a btree. Per suggestion from Ann Harrison of IBPhoenix.	25 years ago

Bruce Momjian	f738747494	Do this TODO item: * HOLDER/HOLDERTAB rename to PROCLOCK/PROCLOCKTAG (Tom) Didn't use PROCLOCKLINK because it made PROCLOCKLINKTAG too long.	25 years ago
Tom Lane	8ca61476e0	Cope with the likelihood that setlocale and localeconv will return pointers to data that will be changed by any later call to setlocale. Must copy what they return to be sure we get the right answer. Karel Zak, further tweaks by Tom Lane.	25 years ago
Tom Lane	dc05a996c5	Fix the setlocale problem in a way that actually works. setlocale returns a string corresponding to the new setting, not the old, therefore the previous patch was quite wrong.	25 years ago
Tom Lane	742d0f25c1	Clean up comments.	25 years ago
Tom Lane	2a314add00	Whoops, I was a tad too enthusiastic about using shared lock mode for SInvalLock. GetSnapshotData(true) has to use exclusive lock, since it sets MyProc->xmin.	25 years ago
Tom Lane	6fdf7bed60	Fixes for datetime-related regress tests, from Tom Lockhart.	25 years ago
Hiroshi Inoue	53b2e00491	Keep the contents of ItemPointerData not the pointers so that per tuple memory context doesn't discard them.	25 years ago
Tom Lane	793bcc67b2	Remove mistakenly-included file, per request from John Gray.	25 years ago
Tom Lane	e3831d83a7	timetz test was omitted from parallel_schedule.	25 years ago
Tom Lane	c0bff32c84	Update horology-no-DST-before-1970.out for new horology test. Still need an update for horology-solaris-1947.out ...	25 years ago
Tom Lane	499abb0c0f	Implement new 'lightweight lock manager' that's intermediate between existing lock manager and spinlocks: it understands exclusive vs shared lock but has few other fancy features. Replace most uses of spinlocks with lightweight locks. All remaining uses of spinlocks have very short lock hold times (a few dozen instructions), so tweak spinlock backoff code to work efficiently given this assumption. All per my proposal on pghackers 26-Sep-01.	25 years ago
Bruce Momjian	818fb55ac4	I have made three changes to the rtree code: one bug fix and two performance improvements. I put an explanation of the changes at http://cs1.cs.nyu.edu/been/postgres-rtree.html The performance improvements are quite significant. All the changes are in the file src/backend/access/rtree/rtree.c I was working with the 7.1.3 code. I'm including the diff output as an attachment. Kenneth Been	25 years ago
Bruce Momjian	7d94ac3b23	Found type mismatch in random.c. Please apply this also. Marko Kreen	25 years ago
Bruce Momjian	cff23429d6	I noticed that the contrib Makefiles were reorganized. Converted pgcrypto one too. * Changed default randomness source to libc random() That way pgcrypto does not have any external dependencies and should work everywhere. * Re-enabled pgcrypto build in contrib/makefile * contrib/README update - there is more stuff than only 'hash functions' * Noted the libc random fact in README.pgcrypto Marko Kreen	25 years ago
Bruce Momjian	850ba41677	A couple of lines were missing from my last patch - this one fixes things. Liam Stewart	25 years ago
Bruce Momjian	40cd81cff4	This is a simple patch to put double quotes around a few cases in pg_ctl.sh which were unquoted when inside of []. Justin Clift	25 years ago
Bruce Momjian	07ce9fe61d	Per the recent discussion there's been some code changes in JDBC's DatabaseMetaData.getColumn(). I proposed a patch that would change the number of queries to find out all columns in a table from 2 * N + 1 to 1 (N being the number of columns reported) by using some outer joins. I also fixed the fact that getColumns() only returned columns that had a default defined. OTOH, I did not use to change the code required for obtaining a column's remarks (by using col_description() for 7.2 and requested by Tom Lane). Finally, I have found a way to get all the column details in a single query and use col_description() for 7.2 servers. A patch is attached. It overrules Ren? Pijlman's fix for this that was committed just today, but still used N + 1 queries (sorry Ren? ;-) ) I also fixed the return values for TABLE_CAT and TABLE_SCHEM from "" to null, to be more standard compliant (and requested in Ren?'s mail found at http://fts.postgresql.org/db/mw/msg.html?mid=1034253). As always, the JDBC1 version has not been tested as I have no JDK 1.1 Jeroen van Vianen	25 years ago

Thomas G. Lockhart	0b268e5d88	Fix markup to allow compilation. The chapters on failure and recovery need more work, but at least they have something now.	25 years ago

Thomas G. Lockhart	f9681968e0	Add information on new timestamp and timestamptz data types. Start chapter on recovery techniques. Still needs work for release.	25 years ago
Thomas G. Lockhart	6f58115ddd	Measure the current transaction time to milliseconds. Define a new function, GetCurrentTransactionStartTimeUsec() to get the time to this precision. Allow now() and timestamp 'now' to use this higher precision result so we now have fractional seconds in this "constant". Add timestamp without time zone type. Move previous timestamp type to timestamp with time zone. Accept another ISO variant for date/time values: yyyy-mm-ddThh:mm:ss (note the "T" separating the day from hours information). Remove 'current' from date/time types; convert to 'now' in input. Separate time and timetz regression tests. Separate timestamp and timestamptz regression test.	25 years ago
Thomas G. Lockhart	1f075a32ee	Add separate regression tests for timetz and the new timestamptz type. Modify the timestamp test to reflect the "no time zone" behavior of this new code; timestamptz resembles the old timestamp code.	25 years ago
Bruce Momjian	44f18333b7	Put MD5 salt at the end for security.	25 years ago
Tom Lane	90aebf7f52	Move s_lock.c and spin.c into lmgr subdirectory, which seems a much more reasonable location for them.	25 years ago

Bruce Momjian	19656b7445	Improve postgresql.conf descriptions.	25 years ago
Tom Lane	cdd9146863	The trailing semicolon in a plpgsql function definition is now optional. Per gripe 9/26.	25 years ago
Tom Lane	d435592f33	Repair oversight in recent changes to index-creation: tuple time qual check can return HEAPTUPLE_INSERT_IN_PROGRESS or HEAPTUPLE_DELETE_IN_PROGRESS, even though we have ShareLock on the relation. To wit, this can happen if the tuple was inserted/deleted by our own transaction. Per report from Justin Clift 9/23.	25 years ago
Tom Lane	1481b3b28b	Remove useless test for time field in pg_control being > 0. We don't need this, and it will create a Y2038 failure. Per report from David Wheeler, who is evidently running on a platform where time_t is already negative.	25 years ago
Bruce Momjian	3e9014d02c	Add ALIGN() for cred packet, for OpenBSD.	25 years ago
Bruce Momjian	be83aac6d2	Disable local creds on OpenBSD because it doesn't support it. Document supported platforms in pg_hba.conf.	25 years ago
