title: Postgres server is not visible in pgadmin
body: <p>I have a newly instantiated postgres server that I generated from a database dump: </p>
  
  <pre><code>psql -U postgres postgres &lt; dump.sql
  </code></pre>
  
  <p>Verifying the installation</p>
  
  <pre><code>sudo pg_lsclusters
  Ver Cluster Port Status Owner    Data directory              Log file
  10  main    5432 online postgres /var/lib/postgresql/10/main /var/log/postgresql
  </code></pre>
  
  <p>/postgresql-10-main.log</p>
  
  <p>Now I then enter pgadmin by typing</p>
  
  <pre><code>pgadmin4
  </code></pre>
  
  <p>In the terminal and no databases are available. I'm using postgres 10(the same as the server for the dump) and ubuntu 16. My postgres setup is pretty standard but with postgres/pg_hba.conf changed to trusted.</p>
  
  <p>Any suggestions?</p>
