ZF-6311: Zend_Db_Adapter_Pdo_Abstract cannot be serialized


Any instance that use Zend_Db_Adapter_Abstract cannot be serialized (for example save the object in session) because the object try to serialize a PDO connection.

:: Error: You cannot serialize or unserialize PDO instances

:: Trace:

0 [internal function]: PDO->__sleep()


I changed the affect versions, because I notice that this bug it's corrected in the trunk version.

A fix was added in release 1.8.0.
