Hi Claiton, thanks for filing this bug report, although this doesn't seem to be related to the Keystone charm, so I will mark it as "invalid" (if you disagree, please set it back to new and let us know how keystone is related in this problem), but also I will add a task for mattermost-k8s which seems to be the workload you want to run.

Best,

Given the crash is happening in postgresql charm code, I believe the bug is probably there.
