title: Impossible to connect to a PostgreSQL server after a new installation
body: <p>I have installed postgresql on my new laptop (on Windows).</p>
  <p>I see the service <code>postgresql-x64-11 - PostgreSQL Server 11</code> is running and is automatic. Perfect.</p>
  <p>I have installed &quot;dbeaver&quot; (21.21). I would like to create my first database via dbeaver. I always get this message:</p>
  <blockquote>
  <p>Database postgres does not exist</p>
  </blockquote>

  <p>Is it possible to create a database with dbeaver ? Or not ? Or must I do the creation with some command lines ?</p>
