Comment 9 for bug 1914415

I've built a custom version of the charm using the latest commit and published it to cs:~mthaddon/postgresql-k8s.

I've then spun up a juju k8s model and ran the following immediately after each other:

juju deploy cs:~mthaddon/postgresql-k8s postgresql
juju deploy cs:~mattermost-charmers/mattermost
juju add-relation mattermost postgresql:db

This worked fine, and I didn't experience the KeyError issue, so I think the fix is good. Would be good if others could confirm.

I did see the following error in debug-log - https://pastebin.ubuntu.com/p/skt8Jq8xB7/ - but things continued fine without my intervention (my model-config has automatically-retry-hooks set to true, which I believe is the default), but that's unrelated I believe.
