      * Making any other change in the content of edata is not considered
      * supported.

      * Note: the reason why the hook can only turn off output_to_server, and

      * all if errstart() deems the message uninteresting.  A hook that could

      * where it would have much less information available.  emit_log_hook is
      * intended for custom log filtering and custom log message transmission
      * mechanisms.
      *
      * The log hook has access to both the translated and original English
      * error message text, which is passed through to allow it to be used as a
      * message identifier. Note that the original text is not available for
