That's explained in the documentation extract already quoted:
if you do use a bad user/db/password, the server will log a message
about that, since it just sees a failed connection attempt. If you'd
rather not have such chatter in your log, then you want to give
pg_isready valid connection data. But that's incidental to the
purpose of the program.
