 New Comment:

The manual (or further sources) does not state, that
PDOStatement::execute() can't be overridden or that PDO::prepare()
returns a somewhat castrated object.

var_dump($stmt) identifies $stmt as of MTFrame_DB_PDOStatement, just as
in my "reproduce code". But the object lacks method foo(). Better said,
the object acts, as if it was a plain PDOStatement. This is no
expected, please correct me.

Description:
------------
When i try to override PDO_Statement::execute(), my Method is ignored
completly.

When i try to implement ::foo() in my extending class, PHP states it is
undefined.

Reproduce code:
---------------
<?php

class MTFrame_DB_PDOStatement extends PDOStatement
{

    public function execute()
    {
        throw new Exception();
        // Nothing happens, i'm ignored
    }

    public function foo()
    {
        throw new Exception();
        // i do not exist?
    }
}

class MTFrame_DB_PDO extends PDO
{
    function prepare($sql)
    {
        return parent::prepare($sql,
array(PDO_ATTR_STATEMENT_CLASS=>array('MTFrame_DB_PDOStatement')));
    }
    
    function query($sql)
    {
        $stmt = parent::prepare($sql,
array(PDO_ATTR_STATEMENT_CLASS=>array('MTFrame_DB_PDOStatement')));
        $stmt->foo();
        return $stmt;
    }
}

?>

Actual result:
--------------
MTFrame_DB_PDOStatement::execute() gets ignored.

calling ::foo() produces:
Call to undefined method MTFrame_DB_PDOStatement::foo()
