And weirder.

So I purged the V1 server again, edited the postgresql.conf file to put it
back to port 5432, reinstalled the V12 package, and now:

stan(at)stantest:~/src/pgemailaddr-master$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
11 main 5432 online postgres /var/lib/postgresql/11/main
/var/log/postgresql/postgresql-11-main.log
12 main 5434 online postgres /var/lib/postgresql/12/main
/var/log/postgresql/postgresql-12-main.log

So, I decided to take a quick look at the production machine, just to make
sure this matched up to what was going on over there, and look what I found:

stan(at)ica-db:~$ htop
stan(at)ica-db:~$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
11 main 5432 online postgres /var/lib/postgresql/11/main
/var/log/postgresql/postgresql-11-main.log
12 main 5432 online postgres /var/lib/postgresql/11/main
/var/log/postgresql/postgresql-12-main.log

This seems impossible to me.
