before my post, i used a sql "show columns from fe_users", but in the result
i also had all additional FE user data (inserted by other extensions).
now, within my function i use the $TCA

function columnNamesFromDB () {
  globals $TCA;
  $dbFields = array_keys($TCA[fe_users][columns]);
  $this->removeNoMapFields(&$dbFields);
  [...]
}

this works and saves me a SQL select.

thanks,
