          Reloads a Performance Schema configuration saved earlier
          within the same session using
          ps_setup_save(). For more
          information, see the description of

          This procedure disables binary logging during its execution by
          manipulating the session value of the
          sql_log_bin system variable.
          That is a restricted operation, so the procedure requires
          privileges sufficient to set restricted session variables. See
          Section 7.1.9.1, “System Variable Privileges”.
