How to list the content of a named volume in docker 1.9+? : <p>Docker 1.9 added named volumes, so I..</p>

<pre><code>docker volume create --name postgres-data

docker volume ls 
</code></pre>

<p>and I get</p>

<pre><code>local               postgres-data
</code></pre>

<p>all good so far.. </p>

<p>so how do I see what is in the named volume?  Is there a way to cd to it on the host system.  Like I can for a mounted host directory?</p>
