With keeping the container running, we see SELinux error messages and a sudden crash of the PostgreSQL container. Let's properly shut down the container before using its volume privately mounted into a different container.
This should fix #536 and also reverts previous attempt (#538) to fix the issues with SELinux messages.
Background:
podman's :Z modificator for volumes works the way that the latest container run with the same volume directory mounted with :Z modificator has access, the previous containers are kept running, but access to the shared directory is suddenly removed. That caused the first instance of PostgreSQL server to crash with SIGSEGV actually, while triggering some SELinux error message during that.
