Package: postgresql-common
Version: 184.pgdg90+1
Severity: important

Currently, pg_upgradecluster unconditionally starts the cluster when the 
upgrade is complete. This
makes it impossible to use the hardlink-to-slave method for rapidly upgrading a 
multi node cluster
that's documented on https://www.postgresql.org/docs/9.6/static/pgupgrade.html.

I suggest adding a --no-start option to it that will leave the new cluster 
stopped, making it possible
to do the rest of the work elsewhere.
