title: Podman pull 'official' images from docker hub?
body: <p>No matter what I do, I only ever get a 404 or Error: invalid reference format</p>
  <p>I think it should be podman pull hub.docker.com/_/postgres</p>
  <p>but this doesn't work. I've also tried</p>
  <pre><code>podman pull hub.docker.com/postgres
  
  podman pull hub.docker.com/__/postgres
  
  podman pull hub.docker.com/library/postgres
  </code></pre>
  <p>Any ideas what's needed here to grab any of the official images from Docker Hub?</p>
