It looks like it's interference from systemd here. The problem is
easily reproduced by putting '-t 0' into pg_ctl.conf:
● postgresql@10-main.service - PostgreSQL Cluster 10-main Loaded: loaded (/lib/systemd/system/postgresql@.service;

In other words, systemd will by default stop a service that fails to
start.
I'm investigating if it's a good idea to tell systemd to ignore the
exit code of pg_ctl(cluster). Possibly moving to Type=notify is the
best solution, but not all majors support that yet.
Will report back once I have a solution.
