why add a begin/commit if I only
have SELECT statements
there (in the default mode) and
the data isn't critical to me
(just some player statistics and
notes by other players - i.e.
a statistic or note is ok to be lost
occasionally)?

Also I've changed my PHP-script
to non-persistent connections:

      $options = array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION);
       $db = new PDO(sprintf('pgsql:host=%s port=%u; dbname=%s',
               DBHOST, DBPORT, DBNAME), DBUSER, DBPASS, $options);

and restarted Apache 2.2.3,
but that error is still there:

SQLSTATE[26000]: Invalid sql
statement name: 7 ERROR: prepared

statement "pdo_stmt_0000000a" does not exist
