That's a pretty content-free message, isn't it :-(
There might be more information in the postmaster log. Make sure
you are saving a postmaster log (postmaster should be started without
-S switch, and with stdout and stderr routed to some logfile), and
then see what gets appended to the log when you try to connect.
