At this point can you connect to the Postgres server on your laptop from
another machine?

Best guess, since this is a laptop, the network is not connected until
NetworkManager(or something similar) is active. On my laptop that
happens late in the startup sequence, after Postgres starts. This is
especially true if you are connecting to a wireless AP.

FYI, include the time in your log prefix, it gives some idea of how far
apart the events are happening. Also logging NOTICE and above is a good
place to start. DEBUG buries you in mass of detail which may or may not
be relevant.
