+    COMMENT '
+             Description
+             -----------
+
+             Reloads a saved Performance Schema configuration,
+             so that you can alter the setup for debugging purposes, 
+             but restore it to a previous state.
+             
+             Use the companion procedure - ps_setup_save(), to 
+             save a configuration.
+
+             Requires the SUPER privilege for "SET sql_log_bin = 0;".
+
+             Parameters
+             -----------
+
+             None.
