Looks like a bug. If it still occurs on a current version, report it on our repository: GitHub - zammad/zammad-docker-compose: Zammad Docker images for docker-compose & Kubernetes

Ensure that the postgresql version matches our upstream docker-compose file, because that’s what we package the Zammad containers with.
