$Pdo = new PDO('pgsql:host=localhost;port=5432;dbname=mydb', 'user', 'password');

$options = = array(
    PDO::ATTR_ERRMODE          => PDO::ERRMODE_EXCEPTION,
    PDO::ATTR_CURSOR           => PDO::CURSOR_FWDONLY,
    PDO::ATTR_EMULATE_PREPARES => false
);

$sql = 'INSERT INTO my_table (
            field_a,
            field_b
        ) VALUES (
            :field_a,
            :field_b
        )';

$Pdo->beginTransaction();

$Ps = $Pdo->prepare($sql, $options);

$Ps->execute(array(
    ':field_a' => 'Field A',
    ':field_b' => 'Field B',
    ':field_c' => 'Field C'
));

$Pdo->commit();

Test script:
---------------
$Ps-execute() returns false, but doesn't show an error message telling that there are more columns than in the SQL specified.

In my real case i have more than one SQL statement, because of this i am using a transaction.

Expected result:
----------------
I expect that PHP throw an exception or error

Actual result:
--------------
PHP didn't trigger exception or error and proceed with the code
