Thanks.

As said in the comment in postgresql@.service, there's unfortunately
not too much we can do about it. The problem is in this line:

ConditionPathExists=/etc/postgresql/%I/postgresql.conf

If you need clusters with dashes in the name, remove this line from
the .service file. (The downside is that you can then start services
called postgresql@what-ever and end up with "failed" bogus services.)
