The probable cause is something connecting to port 5432 and then
disconnecting without sending anything. The fact that the occurrences
are exactly a minute apart suggests that it's some sort of monitoring
tool. I've heard that there's stuff out there that makes a cheesy probe
that Postgres is "up" by just seeing if it can connect to 5432.
