title: postgres on docker fails with `chown: cannot dereference ... : No such file or directory`
body: <p>I am trying to deploy <code>postgres</code> on docker and it exits immediately after I run it. On checking the logs I get the following error:</p>
  <pre><code>chown: cannot dereference '/var/lib/postgresql/data/venv/bin/python3': No such file or directory
  </code></pre>
  <p>The command am running is here below:</p>
  <pre><code>sudo docker run -p 5432:5432 -e POSTGRES_USER=superset -e POSTGRES_PASSWORD=mypostgrespassword -e POSTGRES_DB=superset --volume $PWD:/var/lib/postgresql/data -d postgres
  </code></pre>
  <p>How can I fix that?</p>
