Remove postgresql service from systemctl after upgrade

Question

After upgrading Postgresql version on Debian, I noticed that the old version of postgres continues to appear.

$ systemctl | grep postgresql

[email protected]    loaded failed failed     PostgreSQL Cluster oldversion-main

[email protected]    loaded active running      PostgreSQL Cluster newversion-main

How can I remove "oldversion"?

PS. I've already removed "oldversion" using apt-get remove

Thanks

I've faced the same problem after upgrading from 9.4 to 9.6 from jessie-backports. You only have to reset the failed state of the 9.4 cluster:

# systemctl reset-failed
