these versions adhere to the backend protocol better than previous version
fixes problem when an error occurs on the backend, and the connection is still used
previous versions were throwing an exception half way through the protocol, leaving it
indeterminate.
also removes empty query code, should speed things up a bit
* Introduces a new class, StartupPacket.
* Moves a lot of constants from Connection to StartupPacket.
* Makes two instance variables in Connection into locals.
in the current code, the authentication logic (check user, check the
relation we're operating on, etc) is done in tcop/utility.c, whereas the
actual TRUNCATE command in done in TruncateRelation() in
commands/createinh.c (which is really just a wrapper over
heap_truncate() in catalog/heap.c). This patch moves the authentication
logic into TruncateRelation(), as well as making some minor code
cleanups.

* We should not even consider checking the row if it is no longer
* valid since it was either deleted (doesn't matter) or updated
* (in which case it'll be checked with its final values).

Therein lies the problem... :)
Since it appears you have the requirement of supporting old python
versions, attached is just the pgdb.py part of the patch (with a fix for
DateTime handling). It has the same functionality but certainly won't be
quite as fast. Given the absence of _PyString_Join in python1.5, it's a
pain to get the C variants working for all versions. The pgdb.py patch
does leaves the hooks in, should someone wish to do the optimization at a
later point.

If one is trying to compile a JDBC 1 driver and junit.jar is in the
CLASSPATH, then the build fails as ant tries to build the JDBC 2 test
classes. This patch fixes this problem by excluding the jdbc 2 files
unless the jdk1.2+ property is set.
before a data item is now always skipped, rather than only sometimes.
Backslashes not within double-quoted text are treated reasonably, as
are multiple sequences of quoted text in a single data item. But it
still seems rather prone to misbehavior if the input is not completely
syntactically correct --- in particular, garbage following a right brace
will be ignored.
previously it was throwing a SQLException as soon as the error message was
received from the backend. This did not allow the protocol to finish properly
now, simply collects error messages from the backend until the query is done
and throws exception at the end
Also added setLogLevel to Driver.java, and made the log levels public
per recent pghackers discussion: force a new WAL record at first nextval
after a checkpoint, and ensure that xlog is flushed to disk if a nextval
record is the only thing emitted by a transaction.
src/GNUmakefile.in to src/Makefile
and

All configure substitutions are now done in Makefile.global.
now has an RTE of its own, and references to its outputs now are Vars
referencing the JOIN RTE, rather than CASE-expressions. This allows
reverse-listing in ruleutils.c to use the correct alias easily, rather
than painfully reverse-engineering the alias namespace as it used to do.
Also, nested FULL JOINs work correctly, because the result of the inner
joins are simple Vars that the planner can cope with. This fixes a bug
reported a couple times now, notably by Tatsuo on 18-Nov-01. The alias
Vars are expanded into COALESCE expressions where needed at the very end
of planning, rather than during parsing.
Also, beginnings of support for showing plan qualifier expressions in
EXPLAIN. There are probably still cases that need work.
initdb forced due to change of stored-rule representation.
1) Put back the error message for SQLError().
2) Change Disallow premature to handle the SELECTed
result.
3) Put back the behavior of AUTUCOMMIT mode change.
4) Fix SQLColumns for ODBC3.0.
5) Improve the handling of variable bookmark in ODBC3.0.
6) Enable Recognize Unique Index Button.
