It's not necessary, you "only" have to separate services, one
thing that manages the services files in the Debian packages. It also
manages clusters init and stop/start/etc globally for services named :

- postgresql@10-cluster1
- postgresql@10-cluster2
- ...

Please don't, you'll regret it when you'll have to upgrade as you'll have
to uprade all your binaries. You should create separated services
files and a global one.
