Package: postgresql
Version: 9.6+181
Severity: normal

Dear Maintainer,

I recently upgraded my server which pulled in 9.6.  Then I manually 
migrated the configuration and data and then I purged the old version 

# apt-get purge postgresql-9.4  postgresql-client-9.4 postgresql-contrib-9.4 postgresql-doc-9.4

Surprisingly that also stopped my 9.6 instance and the service disappeared:

# systemctl |grep postgresql
  system-postgresql.slice                                                                                                        loaded    active active    system-postgresql.slice

To restore service, I did

# dpkg-reconfigure postgresql-9.6
# systemctl |grep postgresql
  postgresql.service                                                                                                             loaded    active exited    PostgreSQL RDBMS
  postgresql at 9.6-main.service                                                                                                    loaded    active running   PostgreSQL Cluster 9.6-main
  system-postgresql.slice                                                                                                        loaded    active active    system-postgresql.slice

To me this appears to be defective, and apologize if I missed an existing
report or if this should be filed against another package.
