FYI: It's very common to get these messages in your log file if you have
something like nagios or other monitoring tools checking to see if postgres is
up. This is because many of them just test to see if something is listening on
the port, without opening a proper postgres connection (i.e. telnet localhost
5432). The just connect to the port then disconnect without sending any data of
any kind.
