  @trigger_error('db_field_set_default() is deprecated in drupal:8.0.0. It will be removed from drupal:9.0.0. Instead, get a database connection injected into your service from the container, get its schema driver, and call changeField() on it, passing a full field specification. For example, $injected_database->schema()->changeField($table, $field, $field_new, $spec, $keys_new). See https://www.drupal.org/node/2993033', E_USER_DEPRECATED);
  return Database::getConnection()
