When using PDO::ATTR_STATEMENT_CLASS the statement object is an object
of the user defined class but it's not possible to access it's
(non-pdo) methods

prepare('SELECT login_id FROM logins', $opts);
var_dump($r->foo());
?>
Expected result:
myStatement::foo()
Actual result:
--
Fatal error: Call to undefined method myStatement::foo()

The code you use does work, ok.
But it has nothing to do with the Bug.
Please use the "Reproduce code".

Works in php 5.1:
php -r 'class T extends PDO{function
exec(){var_dump("myexec");}function f(){}}$o=new
T("sqlite::memory:");$o->exec();ReflectionClass::export("T");'
PDO doesn't support 5.0 atm.

method_exists() returning true but the actual call failing is
bewildering to say the least

array('MTFrame_DB_PDOStatement')));
}
}
$m = new MTFrame_DB_PDO('sqlite:mydb.sq3');
$stmt = $m->prepare("SELECT COUNT(*) FROM sqlite_master WHERE
type='table'");
if ( method_exists($stmt, 'foo') )
$stmt->foo();
else
echo 'no such method';
?>

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:
---
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()
