Review Comment:
   I digged a bit deeper, and it seems that the `podman cp ... | tar` command 
produces weird tar files in some cases:
   
   ```
   $ podman cp clever_austin:/var/lib/postgresql/ - | tar t | head
   tar: Removing leading `/' from member names
   /
   /18
   /18/docker
   /18/docker/PG_VERSION
   ```
   
   For other paths, the output is what I would have expected:
   ```
   $ podman cp clever_austin:/etc/ - | tar t | head
   etc
   etc/alpine-release
   etc/apk
   etc/apk/arch
   ```
