pg_ctl will send SIGINT to the postmaster when the service is stopped,
or when windows is shutting down. 

Do you get anything about the postgresql service in the eventlog within
say a minute of this happening? (before or after)

Could it be a backend or the postmaster trying to send a signal to a
different backend, that for some reason sends it to the wrong process?
