[TYPO3-core] RFC #11047: DBAL does not support CLOB/BLOB when using a mapped table name

Same problem arises when mapping fields actually:

$TYPO3_CONF_VARS['EXTCONF']['dbal']['mapping'] = array(
         'tx_templavoila_datastructure' => array(
                 'mapTableName' => 'tx_templavoila_ds',
                 'mapFieldNames' => array(
                         'dataprot' => 'my_dataprot',
                 ),
         ),
);

v2 fixes this too (for completeness).
