	completely.

	along the lines of the following patch to clarify it.  Thanks.
	
	(Alternatively, perhaps the code could maintain a count of nested
	calls to SPI_connect/SPI_finish.  But I didn't try to write that
	patch.)

	* configure, configure.in: 
	jump version to beta3 ... beta2 was created and pulled due to a
	couple of large-ish bugs that Tom and Vadim were able to fix, but
	to avoid any confusion, beta2 was removed ... and for tag'ng
	purposes, beta3 is being created ...

2001-01-09 05:54  ishii

	* src/backend/: access/transam/xlog.c, utils/misc/guc.c: 1.
	Checkpoint.undo may be after checkpoint itself:    - no more
	elog(STOP) in StartupXLOG();	- both checkpoint' undo & redo are
	used to define	    oldest on-line log file.  2. Ability to
	pre-allocate a few log files at checkpoint time    (wal_files
	option). Off by default.

	* src/: backend/optimizer/util/tlist.c, include/optimizer/tlist.h,
	backend/optimizer/plan/setrefs.c,
	backend/optimizer/plan/subselect.c: Fix oversight in planning of
	GROUP queries: when an expression is used as both a GROUP BY item
	and an output expression, the top-level Group node should just copy
	up the evaluated expression value from its input, rather than
	re-evaluating the expression.  Aside from any performance benefit
	this might offer, this avoids a crash when there is a sub-SELECT in
	said expression.

	template0.

2001-01-08 18:07  tgl

	tableoid, which for some reason were never yet mentioned anywhere
	in our documentation.  Improve explanations of the other system
	attributes, too.

2001-01-08 17:30  tgl

	* doc/src/sgml/ref/select.sgml: Document that we don't support
	ORDER BY with general expressions on the output of
	UNION/INTERSECT/EXCEPT.

2001-01-08 17:01  petere

	* doc/src/sgml/runtime.sgml: Add rudimentary section about

2001-01-08 16:54  momjian

	* doc/TODO.detail/flock, doc/TODO.detail/memory,
	src/backend/parser/analyze.c: Remove compiler warning about
	uninitialized warnings.

	DB, not only the last one.

	code (ifdef'd out in normal use).

2001-01-08 14:31  tgl

	* src/backend/storage/buffer/bufmgr.c: LockBuffer should not elog
	while holding buffer's cntx_lock.

2001-01-07 23:14  inoue

	* src/backend/commands/command.c: Keep relations open until they
	are no longer needed.

2001-01-07 20:31  tgl

	* src/backend/nodes/: outfuncs.c, readfuncs.c: Make
	outfuncs/readfuncs treat OIDs properly as unsigned values.  Clean
	up inconsistent coding practices for handling Index values and
	booleans, too.

2001-01-07 18:14  tgl

	* src/backend/access/heap/heapam.c: Correct nasty error in
	heap_update: it was releasing the buffer refcount before calling
	RelationInvalidateHeapTuple(), which is bad because the latter
	needs to look at the tuple data, which is in the shared disk
	buffer.  If another backend manages to recycle the buffer while
	this is going on, we will compute the wrong hashindex for the tuple
	or maybe even crash outright.  Must hold buffer refcount until
	afterwards.  (This bug is not in 7.0.*; seems to be have introduced
	during WAL changes.)

2001-01-07 00:30  tgl

	* src/backend/storage/ipc/ipc.c: Clear QueryCancel and
	ProcDiePending at start of proc_exit, to ensure that leftover
	cancel/die requests cannot interfere with exit activities.

2001-01-07 00:17  tgl

	* src/: include/miscadmin.h, include/utils/elog.h,
	backend/tcop/postgres.c, backend/utils/init/globals.c: Fix recent

	* src/: backend/nodes/outfuncs.c, backend/nodes/read.c,
	backend/nodes/readfuncs.c, include/catalog/catversion.h,
	include/nodes/readfuncs.h: Modify readfuncs so that recursive use
	of stringToNode will not crash and burn.  Just for added luck,
	change reading of CONST nodes so that we do not need to consult
	pg_type rows while reading them; this means that no database access
	occurs during stringToNode.  This requires changing the order in
	which const-node fields are written, which means an initdb is
	forced.

2001-01-06 20:05  tgl

	* src/backend/commands/command.c: Clean up checking of relkind for
	ALTER TABLE and LOCK TABLE commands.  Disallow cases like adding
	constraints to sequences :-(, and eliminate now-unnecessary search
	of pg_rewrite to decide if a relation is a view.

2001-01-06 17:59  tgl

	* src/backend/utils/mmgr/aset.c: Log memory context stats to stderr
	when reporting a 'Memory exhausted' error, so as to provide a
	starting point for debugging.

2001-01-06 17:53  tgl

	* src/backend/utils/cache/relcache.c: Fix memory leak in relcache
	handling of rules: allocate rule parsetrees in per-entry
	sub-memory-context, where they were supposed to go, rather than in
	CacheMemoryContext where the code was putting them.  Must've
	suffered a severe brain fade when I wrote this :-(

2001-01-06 17:24  petere

	* GNUmakefile.in: Use more portable syntax for 'find'.

2001-01-06 16:57  petere

	* src/bin/pg_dump/: pg_dump.c, pg_restore.c: Polish help output. 
	Allow --help to work with BSD getopts.

	* doc/src/sgml/: datetime.sgml, filelist.sgml, keywords.sgml,
	syntax.sgml, user.sgml: Update section on SQL syntax.  (Still a lot
	to be done though.)  Add appendix with comprehensive list of key
	words.

2001-01-06 06:50  petere

	* src/backend/parser/gram.y: Simplify the rules that explicitly
	allowed TYPE as a type name (which is no longer the case).  Add AND
	and TRAILING to ColLabel.  All key words except AS are now at least
	ColLabel's.

2001-01-06 00:14  tgl

	* doc/src/sgml/ref/create_rule.sgml: Bring CREATE RULE reference
	page into some semblance of agreement with what's actually
	implemented.

2001-01-05 23:33  ishii

	* src/backend/commands/copy.c: Fix copy to make it more robust
	against unexpected character sequences. This is done by disabling
	multi-byte awareness when it's not necessary. This is kind of a
	workaround, not a perfect solution.  However, there is no ideal way
	to parse broken multi-byte character sequences. So I guess this is
	the best way what we could do right now...

2001-01-05 21:48  inoue

	* src/backend/utils/cache/relcache.c: init_irels() is changed to be
	called in RelationCacheInitializePhase2() so that transactional
	control could guarantee the consistency.

	variables (doesn't look like it could ever have worked...)

2001-01-05 18:54  tgl

	* src/: backend/utils/cache/catcache.c,
	backend/utils/cache/inval.c, include/utils/catcache.h: Rename and
	document some invalidation routines to make it clearer that they
	don't themselves flush any cache entries, only add to to-do lists
	that will be processed later.

	src/interfaces/ecpg/preproc/preproc.y,
	src/test/regress/sql/inherit.sql,

	implementation of CREATE TABLE's UNDER clause, and revert
	documentation to describe the existing INHERITS clause instead, per
	recent discussion in pghackers.  Also fix implementation of
	SQL_inheritance SET variable: it is not cool to look at this var
	during the initial parsing phase, only during parse_analyze().	See
	recent bug report concerning misinterpretation of date constants
	just after a SET TIMEZONE command.  gram.y really has to be an
	invariant transformation of the query string to a raw parsetree;
	anything that can vary with time must be done during parse
	analysis.

	* src/backend/commands/creatinh.c: Disallow creation of a child

	* configure, configure.in: Allow NetBSD's libedit to be used

	* src/backend/utils/adt/timestamp.c: Repair always-broken
	date_part('quarter',timestamp).  Previous result did not have
	correct month boundaries so anything near edge	cases was suspect
	(e.g. April was in Q1 and July, August were lumped into  Q2).

	starting a new hashtable search no longer clobbers any other search
	active anywhere in the system.	Fix RelationCacheInvalidate() so

	backend/access/transam/xlog.c, backend/storage/buffer/bufmgr.c: Fix
	failure in CreateCheckPoint on some Alpha boxes --- it's not OK to

	* src/interfaces/jdbc/org/postgresql/:
	jdbc1/PreparedStatement.java, jdbc1/ResultSet.java,
	jdbc2/PreparedStatement.java, jdbc2/ResultSet.java: Attached are
	patches for two fixes to reduce memory usage by the JDBC drivers.
	
	The first fix fixes the PreparedStatement object to not allocate
	unnecessary objects when converting native types to Stings.  The
	old code used the following format:	    (new
	Integer(x)).toString() whereas this can more efficiently be
	occompilshed by:	 Integer.toString(x); avoiding the
	unnecessary object creation.
	
	The second fix is to release some resources on the close() of a
	ResultSet.  Currently the close() method on ResultSet is a noop. 
	The purpose of the close() method is to release resources when the
	ResultSet is no longer needed.	The fix is to free the tuples
	cached by the ResultSet when it is closed (by clearing out the
	Vector object that stores the tuples).	This is important for my
	application, as I have a cache of Statement objects that I reuse. 
	Since the Statement object maintains a reference to the ResultSet
	and the ResultSet kept references to the old tuples, my cache was
	holding on to a lot of memory.

	* src/interfaces/jdbc/org/postgresql/Connection.java: In looking at

	support character set encodings.  However I noticed that the
	encoding that is used isn't obtained from the DB.  Since Java uses
	unicode UCS2 internally the character set encoding is used to
	translate strings from/to the DB encoding.  So it seems logical
	that the code would get the encoding from the DB instead of the
	current method of requiring the user pass it as a parameter.
	
	Attached is a patch that gets the DB encoding from the DB in the
	same manner as is done in libpq/fe-connect.c.  The patch is created
	off of the latest CVS sources (Connection.java version 1.10).

	is not released at transaction commit (but it is released on
	transaction abort, to ensure recovery after an elog(ERROR)).  In
	VACUUM, use a session lock to protect the master table while
	vacuuming a TOAST table, so that the TOAST table can be done in an
	independent transaction.
	
	I also took this opportunity to do some cleanup and renaming in the
	lock code.  The previously noted bug in ProcLockWakeup, that it
	couldn't wake up any waiters beyond the first non-wakeable waiter,
	is now fixed.  Also found a previously unknown bug of the same kind
	(failure to scan all members of a lock queue in some cases) in
