That's why "simple-cuirass-services" > returns three services. Maybe you see another way? When a service extends a service type, an instance of that service type is automatically added if it=E2=80=99s missing (provided that service type = has a default value). This happens in =E2=80=98instantiate-missing-services=E2= =80=99. So, if postgresql-role-service-type and postgresql-service-type have a default value, simple-cuirass-service could extend them both (possibly with a dummy value) and it would just work. HTH!
