https://www.postgresql.org/docs/9.6/static/pgupgrade.html
"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. You can use the same port number for both clusters
when doing an upgrade because the old and new clusters will not be
running at the same time. However, when checking an old running server,
the old and new port numbers must be different."
