Docker Compose - Error while starting DB container

I have currently the same issue described here [https://github.com/ckan/ckan/issues/6027](https://github.com/ckan/ckan/issues/6027) during starting db with `docker compose -f docker-compose.yml up` by getting the error `initdb: directory "/var/lib/postgresql/data" exists but is not empty`. A change of `pg_data=/var/lib/postgresql/data/db` or running `docker system prune` before don't work. I had no problems with the last week installed ckan-docker.

Does anybody have the same issue now!?
