I'm not sure that it's really necessary to save insert events when there
are only after update or delete triggers, but certainly it's wrong for
COPY to behave differently from an INSERT query.
detect case that next page in log came from an older run than the prior
page. This avoids the necessity to re-zero the log after recovery from
a crash, which is good because we need not risk destroying valuable log
information.
This forces another initdb since yesterday :-(. Need to get that log
reset utility done...
ODBC driver on Windows 9X/ME/NT/2K when using the later versions of the
driver that don't have the Installshield installation:
1) Install psqlodbc.dll in to C:\Windows\System or C:\Winnt\System32
2) Add the registry settings in the attached file using regedit.
A useful addition to src/interfaces/odbc perhaps?
Regards, Dave.
* Store two past checkpoint locations, not just one, in pg_control.
On startup, we fall back to the older checkpoint if the newer one
is unreadable. Also, a physical copy of the newest checkpoint record
is kept in pg_control for possible use in disaster recovery (ie,
complete loss of pg_xlog). Also add a version number for pg_control
itself. Remove archdir from pg_control; it ought to be a GUC
parameter, not a special case (not that it's implemented yet anyway).
* Suppress successive checkpoint records when nothing has been entered
in the WAL log since the last one. This is not so much to avoid I/O
as to make it actually useful to keep track of the last two
checkpoints. If the things are right next to each other then there's
not a lot of redundancy gained...
* Change CRC scheme to a true 64-bit CRC, not a pair of 32-bit CRCs
on alternate bytes. Polynomial borrowed from ECMA DLT1 standard.
* Fix XLOG record length handling so that it will work at BLCKSZ = 32k.
* Change XID allocation to work more like OID allocation. (This is of
dubious necessity, but I think it's a good idea anyway.)
* Fix a number of minor bugs, such as off-by-one logic for XLOG file
wraparound at the 4 gig mark.
* Add documentation and clean up some coding infelicities; move file
format declarations out to include files where planned contrib
utilities can get at them.
* Checkpoint will now occur every CHECKPOINT_SEGMENTS log segments or
every CHECKPOINT_TIMEOUT seconds, whichever comes first. It is also
possible to force a checkpoint by sending SIGUSR1 to the postmaster
(undocumented feature...)
* Defend against kill -9 postmaster by storing shmem block's key and ID
in postmaster.pid lockfile, and checking at startup to ensure that no
processes are still connected to old shmem block (if it still exists).
* Switch backends to accept SIGQUIT rather than SIGUSR1 for emergency
stop, for symmetry with postmaster and xlog utilities. Clean up signal
handling in bootstrap.c so that xlog utilities launched by postmaster
will react to signals better.
* Standalone bootstrap now grabs lockfile in target directory, as added
insurance against running it in parallel with live postmaster.
tuples inserted/deleted/updated in a single transaction. On my machine,
this reduced the time to delete 80000 tuples in a foreign-key-referencing

of a counted input string. Marinos Yannikos' recent crash report turns
out to be due to applying pg_ascii2wchar_with_len to a TEXT object that
is smack up against the end of memory. This is the second just-barely-
reproducible bug report I have seen that traces to some bit of code
fetching one more byte than it is allowed to. Let's be more careful
out there, boys and girls.
While at it, I changed the code to not risk a similar crash when there
is a truncated multibyte character at the end of an input string. The
output in this case might not be the most reasonable output possible;
if anyone wants to improve it further, step right up...
succeeds or not. Revise rtree page split algorithm to take care about
making a feasible split --- ie, will the incoming tuple actually fit?
Failure to make a feasible split, combined with failure to notice the
failure, account for Jim Stone's recent bug report. I suspect that
hash and gist indices may have the same type of bug, but at least now
we'll get error messages rather than silent failures if so. Also clean
up rtree code to use Datum rather than char* where appropriate.
One more :)) It's for improper function argumets for

bits in JDBC & the first set of tools into contrib.
This is the third, and deals with enabling JDBC to be compiled with the main
source.
What it does is add a new option to configure: --with-java
This option tells configure to look for ant (our build tool of choice) and
if found, it then compiles both the JDBC driver and the new tools as part
of the normal make.
Also, when the postgresql install is done, all the .jar files are also
installed into the ${PGLIB}/java directory (thought best to keep then separate)
Now I had some conflicts when this applied so could someone please double check

am talking with Thomas Lockhart about the idea of bringing the PyGreSQL
version number into alignment with PostgreSQL so this may change to 7.1
before the release.
I have added to the copyright to indicate that from now on the PostgreSQL
copyright will apply. If someone wants to make that clearer please do.
The existing copyrights need to stay there for now but if necessary I can
ask Pascal Andre if he agrees to a different wording.
Added reference to the Python DB-API 2.0 compliant API wrapper.
Added reference to the PyGreSQL mailing list.
when user does another FETCH after reaching end of data, or another
FETCH backwards after reaching start. This is needed because some plan
nodes are not very robust about being called again after they've already
returned NULL; for example, MergeJoin will crash in some states but not
others. While the ideal approach would be for them all to handle this
correctly, it seems foolish to assume that no such bugs would creep in
again once cleaned up. Therefore, the most robust answer is to prevent
the situation from arising at all.
noncachable, so that CURRENT_DATE and CURRENT_TIME work as functions
again, rather than being collapsed to constants immediately. Marking the
reverse conversions noncachable might be overkill, but I'm not sure;
do these datatypes have the notion of a CURRENT value? Better safe than
sorry, for now.

Subject: [HACKERS] pgaccess Japanese input capability patch
From: Tatsuo Ishii <t-ishii@sra.co.jp>

Hi Teodorescu,
I have made patches which enable pgaccess to input Japanese characters
in the table editing window. As you might know, to input Japanese
characters, we first type in "hiragana" then convert it to "kanji". To
make this proccess transparent to tcl application programs, libraries
are provided with localized version of Tcl/Tk. The patches bind
certain keys to initiate a function (kanjiInput) that is responsible
for the conversion process. If the function is not available, those
keys will not be binded.
Comments?

only if at least N other backends currently have open transactions. This
is not a great deal of intelligence about whether a delay might be
profitable ... but it beats no intelligence at all. Note that the default
COMMIT_DELAY is still zero --- this new code does nothing unless that
setting is changed.
Also, mark ENABLEFSYNC as a system-wide setting. It's no longer safe to
allow that to be set per-backend, since we may be relying on some other
backend's fsync to have synced the WAL log.
does not lead to a one-second delay, but to an immediate EINVAL failure.
This causes CHECKPOINT to crash with s_lock_stuck much too quickly :-(.
Fix by breaking down the requested wait div/mod 1e6.

It's simple to do the translation, And I've test in 7.0.2 & current CVS,
seems pretty good.
If anyone want this little thing, I'll very happy.
use it is very simple, just gunzip it and copy to
$PGDIR/share/pgaccess/lib/languages/ for current CVS version,
and $PGDIR/pgaccess/lib/languages/ for 7.0*
BTW: I havn't got the tools to translate it to BIG5 encoding, is there
anybody to to it?

rules ('A'-'Z'->'a'-'z' and nothing else). However, once a word is
determined not to be a keyword, it will be case-folded under the current
locale, same as before. See pghackers discussion 20-Feb-01.
be lurking in the install target directory. But don't zap up-to-date

Per suggestion from Larry Rosenman.
use the ANSI varargs style (<stdarg.h>) not the old style. Tatsuo had
reported this change was necessary back in the 7.0 beta cycle (4/13/00)
but for some reason, making the edit never got done.
option of CREATE DATABASE. In pg_regress, create regression database
from template0 to ensure that any installation-local cruft in template1
will not mess up the tests.
waste of cycles on single-CPU machines, and of dubious utility on multi-CPU
machines too.
Tweak s_lock_stuck so that caller can specify timeout interval, and
increase interval before declaring stuck spinlock for buffer locks and XLOG
locks.
On systems that have fdatasync(), use that rather than fsync() to sync WAL
log writes. Ensure that WAL file is entirely allocated during XLogFileInit.
either wrong or unnecessary in most cases, and on systems where setting
status takes a kernel call, the overhead of setting status three times
per command rather than two is annoying.

- Reduced the object overhead in PreparedStatement by reusing the same
StringBuffer object throughout. Similarly SimpleDateStamp's are alse
reused in a thread save manner.
- Implemented in PreparedStatement: setNull(), setDate/Time/Timestamp
using Calendar, setBlob(), setCharacterStream()
- Clob's are now implemented in ResultSet & PreparedStatement!
- Implemented a lot of DatabaseMetaData & ResultSetMetaData methods.
We have about 18 unimplemented methods left in JDBC2 at the current
time.
if the return datatype's input converter was at all strict, because the
converter would get called on junk data when returning NULL. Also
ensure that it gives an error rather than coredumping if someone tries
to use it in a trigger function.
1. If there is exactly one pg_operator entry of the right name and oprkind,
oper() and related routines would return that entry whether its input type
had anything to do with the request or not. This is just premature
optimization: we shouldn't return the single candidate until after we verify
that it really is a valid candidate, ie, is at least coercion-compatible
with the given types.
2. oper() and related routines only promise a coercion-compatible result.
Unfortunately, there were quite a few callers that assumed the returned
operator is binary-compatible with the given datatype; they would proceed
to call it without making any datatype coercions. These callers include
sorting, grouping, aggregation, and VACUUM ANALYZE. In general I think
it is appropriate for these callers to require an exact or binary-compatible
match, so I've added a new routine compatible_oper() that only succeeds if
it can find an operator that doesn't require any run-time conversions.
Callers now call oper() or compatible_oper() depending on whether they are
prepared to deal with type conversion or not.
The upshot of these bugs is revealed by the following silliness in PL/Tcl's
selftest: it creates an operator @< on int4, and then tries to use it to
sort a char(N) column. The system would let it do that :-( (and evidently
has done so since 6.3 :-( :-(). The result in this case was just a silly
sort order, but the reverse combination would've provoked coredump from
trying to dereference integers. With this fix you get more reasonable
behavior:
pltcl_test=# select * from T_pkey1 order by key1, key2 using @<;
ERROR: Unable to identify an operator '@<' for types 'bpchar' and 'bpchar'
You will have to retype this query using an explicit cast
automatically to compensate the lack of automatic
conversion functionality of PostgreSQL server.
For example if there's a numeric type binding
1.2567 --> 1.2567::numeric.
I hope this change would enable the use of numeric
type in MS-Access etc.
Thanks Hiroki Kataoka for his checking my code.
compressed storage works perfectly well. Might as well have a coherent
strategy for applying it, rather than the haphazard store-what-you-get
approach that was in the code before. The strategy I've set up here is
to attempt compression of any compressible index value exceeding
BLCKSZ/16, or about 500 bytes by default.
the old ones were not small enough to ensure r-tree and gist indexes would
get picked when available. These numbers are totally bogus anyway, but
in the absence of any real estimation technique, we'd like to select
indexes when available ...
per recent discussion in pgsql-odbc. Now SELECT is
a boundary but VACUUM isn't.
2) Put back the error handling behavior. When elog(ERROR)
was detected the driver automatically issue "ABORT"
if a transaction is in progress.
3) Driver version is 7.01.0003(Dave already set it but
it was put back).
such as
SELECT f1 FROM foo UNION SELECT ... ORDER BY upper(f1)
to draw
'ORDER BY on a UNION/INTERSECT/EXCEPT result must be on one of the result columns'
rather than the uninformative 'f1 not found' we were producing before.
Eventually this should actually work, but that looks much too hard to try
to implement in late beta...
clause with an alias is a <subquery> and therefore hides table references
appearing within it, according to the spec. This is the same as the
preliminary patch I posted to pgsql-patches yesterday, plus some really
grotty code in ruleutils.c to reverse-list a query tree with the correct
alias name depending on context. I'd rather not have done that, but unless
we want to force another initdb for 7.1, there's no other way for now.
- Fixed bug in LargeObject & BlobOutputStream where the stream's output
was not flushed when either the stream or the blob were closed.
- Fixed PreparedStatement.setBinaryStream() where it ignored the length
Tue Feb 13 16:33:00 GMT 2001 peter@retep.org.uk
- More TestCases implemented. Refined the test suite api's.
- Removed need for SimpleDateFormat in ResultSet.getDate() improving
performance.
- Rewrote ResultSet.getTime() so that it uses JDK api's better.
Tue Feb 13 10:25:00 GMT 2001 peter@retep.org.uk
- Added MiscTest to hold reported problems from users.
- Fixed PGMoney.
- JBuilder4/JDBCExplorer now works with Money fields. Patched Field &
ResultSet (lots of methods) for this one. Also changed cash/money to
return type DOUBLE not DECIMAL. This broke JBuilder as zero scale
BigDecimal's can't have decimal places!
- When a Statement is reused, the previous ResultSet is now closed.
- Removed deprecated call in ResultSet.getTime()
Thu Feb 08 18:53:00 GMT 2001 peter@retep.org.uk
- Changed a couple of settings in DatabaseMetaData where 7.1 now
supports those features
- Implemented the DatabaseMetaData TestCase.
Wed Feb 07 18:06:00 GMT 2001 peter@retep.org.uk
- Added comment to Connection.isClosed() explaining why we deviate from
the JDBC2 specification.
- Fixed bug where the Isolation Level is lost while in autocommit mode.
- Fixed bug where several calls to getTransactionIsolationLevel()
returned the first call's result.

- Add extra arg to formatStringLiteral to specify how to handle LF & TAB.
I opted for encoding them except in procedure bodies & comments
- Fixed bug in tar file input when restoring blobs
definitions from K&R to ANSI C style, and fix broken assumption that
int and long are the same datatype. This repairs problems observed
on Alpha with regexps having between 32 and 63 states.
two transactions create the same table name concurrently, the one that
fails will complain about unique index pg_class_relname_index, rather than
about pg_type_typname_index which'll confuse most people. Free side
benefit: pg_class.reltype is correctly linked to the pg_type entry now.
It's been zero in all but the preloaded pg_class entries since who knows
when.
1) Tidies up the Datasource Dialogue now the version options are gone.
2) Tidies a comment in info.c.
3) Increments all version numbers to 07.01.0003 to take account of recent
revisions.

are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively. By default, only include files meant for frontend use are
installed into the installation include directory. There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.
rather than executing the INTO clause with non-plpgsql semantics
as it was doing for the last few weeks/months. This keeps our options
open for making it do the right plpgsql-ish thing in future without
creating a backwards compatibility problem. There is no loss of
functionality since people can get the same behavior with CREATE TABLE AS.
Add -l option to name log file. Set umask to 077.
Proper file descriptor redirection to allow postmaster to detach from
shell's process group.
Add -s option to turn off informational messages.
any other client connections that may exist (which would only happen if
another client is currently in the authentication cycle). This avoids
wastage of open descriptors in a child. It might also explain peculiar
behaviors like not closing connections when expected, since the kernel
will probably not signal EOF as long as some other backend is randomly
holding open a reference to the connection, even if the client went away
long since ...
The driver version is 07.01.0002 now.
1) initialized pg_version by DSN's protocol info
so that we could always use pg_version info
once a connection is established (pg_version()
didn't exist before 6.4). PROTOCOL_XX() macros
are removed(except from connection.[ch]).
2) provided a few macros to encapsulate connection's
version info and replaced existent comparison
stuff by those macros.
3) change SQLTables() so that 7.1 servers could show
views.
In addtion, the following patch from Dave Page is applied.
This patch fixes a bug in SQLGetInfo for SQL_DBMS_VER which corrupted the
driver version string. The driver version number has also been incremented
to 07.01.0002.
Regards, Dave. <<odbc.diff>>
elog(ERROR) not an Assert trap, since we've downgraded out-of-memory to
elog(ERROR) not a fatal error. Also, change the hard boundary from 256Mb
to 1Gb, just so that anyone who's actually got that much memory to spare
can play with TOAST objects approaching a gigabyte.
- Some minor additions to Statement to make our own extensions more
portable.
- Statement.close() will now call ResultSet.close() rather than just
dissasociating with it.
- Fixed bug where Statement.setMaxRows() was a global setting. Now
limited to just itself.
- Changed LargeObject.read(byte[],int,int) to return the actual number
of bytes read (used to be void).
- LargeObject now supports InputStream's!
- PreparedStatement.setBinaryStream() now works!
- ResultSet.getBinaryStream() now returns an InputStream that doesn't
copy the blob into memory first!
- Connection.isClosed() now tests to see if the connection is still alive
rather than if it thinks it's alive.
allocated by plan nodes are not leaked at end of query. This doesn't
really matter for normal queries, but it sure does for queries invoked
repetitively inside SQL functions. Clean up some other grotty code
associated with tupdescs, and fix a few other memory leaks exposed by
tests with simple SQL functions.
Ok. I have made patches for fixing some of pg_dump problems(see
attached patches). The patches address the problem with user defined
functions, operators and aggregates.
and two 'win32.mak'. Addresses the following:
1) Oops. Spelled fcntl.h wrong in the last one. D'uh.
2) PG_VERSION changed to be defined with " around it. psql/command.c failed
to compile without that.
3) Changed makefiles to use "/MD" and link both psql and libpq.dll against
MSVCRT.DLL instead of a static library. This takes care of the
crash-upon-free in psql.
