   * try to correct the page size during idle based on this value.
   * @note If the database is using the WAL journal mode, the page size won't
  *        be changed to the requested value.  See bug 634374.
   * @note Valid page size values are powers of 2 between 512 and 65536.

   *         opt-out for now, it will be retried later.  Useful when participant
