Ziggy: I suggest you read the pg_upgrade documentation. http://www.postgresql.org/docs/9.4/static/pgupgrade.html Specifically the part where it says: "Obviously, no one should be accessing the clusters during the upgrade. pg_upgrade defaults to running servers on port 50432 to avoid unintended client connections."
