I don't see pattern stored in field data in database?

Disabling textformatters: FieldtypeSomething > init() >

parent::allowTextFormatters(false);

Making the pattern readonly: InputfieldSomething > ___getConfigInputfields() >

$f = $inputfields->get('pattern');

if($f) $f->attr('disabled', 'disabled');

To alter the pattern without reinstalling the Fieldtype, it isn't stored in the database? I can do it via API, but where is it stored? It's missing from the data column of the fields table for the field where all the other attributes are.
