in Turkish locale. Keywords are now checked under pure ASCII case-folding
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
headers (so install-all-headers before regular install will work).
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.
as previously discussed.
It makes AIX and IRIX not use DST for dates before 1970.
The following expected files need to be removed from the regression tests,
they contain wrong results and are not needed any more.
src/test/regress/expected/horology-1947-PDT.out
src/test/regress/expected/tinterval-1947-PDT.out
src/test/regress/expected/abstime-1947-PDT.out

- 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.
Regards, Dave Page
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.
