PHP Bug Type: PDO related
Bug description: Deallocation of prepared statement that hasn't been allocated
under postgresql
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')
