title: pg_restore ignores -j parameter
body: <p>I have quite a large database (15G+ compressed) that was created like this:</p>
  
  <pre><code>pg_dump wrwks_prod -Fc -f /path/to/file.dump
  </code></pre>
  
  <p>and restored to a remote host like this:</p>
  
  <pre><code>pg_restore --no-owner --clean --dbname=dbname --username=user --host=remote_host --port=port  -j 3 --v /path/to/file.dump
  </code></pre>
  
  <p>But when I checked the remote machine, there was only one process using one core for index creation, thus ignoring the jobs parameter.</p>
  
  <p>What could be the reason for this?</p>
  
  <p>Both the local and the remote machine run with Postgres 9.2.</p>
