New Comment:
Transaction failing quietly for no reason is a pretty nasty bug. We
have just spent several hours troubleshooting this problem, and I can
confirm that the bug is 100% on target. If a prepared transaction is
never executed, the transaction will quietly fail.

I would suggest the following patch:

Please try using this CVS snapshot:
http://snaps.php.net/php5.2-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php5.2-win32-latest.zip
Appears to work fine (at least for me) in latest CVS.

Description:
------------
Using PHP 5.1.4 to connect to a postgresql 8.1.4 database, native
prepared statements.
When allocating a prepared statement and then trying to unset it, PDO
attemps to deallocate it even if it never been used (eg. when running a
query against an empty set).
PDO does not throw an exception in such case, but an error such as:
ERROR: prepared statement "pdo_pgsql_stmt_085b2f2c" does not exist
Appers in the server log.
When running inside a transaction, such error aborts it.
Reproduce code:
---------------
$pdo->beginTransaction();
$stmt = $pdo->prepare("SELECT 'never executed'");
unset($stmt);
$res = $pdo->query('SELECT 123');
Actual result:
--------------
PHP Fatal error: Uncaught exception 'PDOException' with message
'SQLSTATE[25P02]: In failed sql transaction: 7 ERROR: current
transaction is aborted, commands ignored until end of transaction
block' in XXX:13
Stack trace:
#0 XXX: PDO->query('SELECT 123')
