More than likely either a port scanner or some program that checks
postgresql for life is simply hitting the port and then dropping the
connection when it sees the answer.  For instance, if I telnet to my
pgsql server / port, I see this for a disconnect:

LOG:  incomplete startup packet

and this for typing in gobbledly gook:
LOG:  invalid length of startup packet
