There are none.  Per the documentation:

    It is not necessary to supply correct user name, password, or
    database name values to obtain the server status; however, if
    incorrect values are provided, the server will log a failed
    connection attempt.

If you don't want log spam about failed connections, you'd need
a user with privilege to connect to the mentioned database.
Otherwise, not.
