Comment 15 for bug 1879645

Some details: Controller is 2.9-rc2. Offering model is IAAS, offering charm is cs:postgresql (focal, channel=edge). Consuming model is CAAS, consuming charm is a mattermost k8s workload charm I'm developing.

I was removing my xenial deployment of postgresql from the IAAS model to redeploy it on focal, as well removing as the mattermost application from the CAAS model to test some charm changes, somewhat at the same time.
