Looks like Juju 2.9 has changed how DNS resolution is working in the pods, and the pod setup is hanging because the k8s service names no longer resolve. Fix is looking like requiring Juju 2.9 (the new feature that I suspect broke things looks like it makes the failing code unnecessary, if I make use of it). I’ll follow up in the PostgreSQL k8s Charm topic to avoid derailing this one further.
