I am not sure whether docker or docker-compose does this and conversely I don't know whether the issue lies with podman or podman-compose:

For postgres containers we often have a setup like this:

services:

  db:
    image: postgres
    restart: always
    environment:
      POSTGRES_PASSWORD: example
    volumes:
    - "./pg-data:/var/lib/postgresql/data"

in docker the folder pg-data is created automatically, if it doesn't exist. Via podman-compose I get

Error: error checking path "/tmp/foo/./pg-data": stat /tmp/foo/./pg-data: no such file or directory
