-   The options <option>--dbname</> and <option>--username</> can be used to avoid gratuitous
-   error messages in the logs, but are not necessary for proper functionality.
+   It is not necessary to supply correct user name, password, or database
+   name values to obtain the server status; however, if incorrect values
