title: Unable to connect to postgresql with pgAdmin4: readonly attribute error
body: <p>I have a local postgresql 10 server (tested the same on 9.6, don't think it's related to the DB at all, only to pgAdmin4, as pgAdmin3 works just fine)</p>
  
  <p>As in the screenshot, I am trying to connect to the localhost db with user postgres on a fresh installation, but I keep receiving this message:</p>
  
  <pre><code>readonly attribute
  </code></pre>
  
  <p>I searched everywhere for this error, but couldn't find any useful solutions or workarounds<a href="https://i.stack.imgur.com/RVIhJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RVIhJ.png" alt="enter image description here"></a></p>
