I agree there's not much there:

These are cases where the client has gone away without shutting down
its connection properly.  At the TCP timeout, the postmaster checks
the client, discovers it isn't there, and shuts down the connection. 
So this tells you that a client disconnected abnormally, but it also
tells you that the postmaster was working correctly then.

And this is your start up attempt.

I doubt it very much.  I think you probably need to increase the
verbosity of your logging in order to make it clearer what's going
on.  Also, timestamps would help: from the output that's there, you
can't tell how long it was between the last known-alive postmaster
event (unexpected EOF) and the start-up attempt.

You'll probably want to send the output through a log rotator if you
increase the verbosity: multi-gig log files aren't so good.
