are defined in the $cfg['RestrictColumnTypes'] and $cfg['RestrictFunctions

$cfg['RestrictColumnTypes'] = array(
'VARCHAR' => 'FUNC_CHAR', [...]
$cfg['RestrictFunctions'] = array(
'FUNC_CHAR' => array(

'CHAR',
'SOUNDEX',
'LCASE',
'UCASE',
'PASSWORD',
'OLD_PASSWORD',

'ENCRYPT',
'COMPRESS',
'UNCOMPRESS',
'LAST_INSERT_ID',
'USER',
'CONCAT'
), [...]
