title: Using DBeaver to query a PostgreSQL db and get following error: SQL Error [0A000]: ERROR: cross-database references are not implemented
body: <p>I am completely new to SQL, PostgreSQL, and DBeaver. When trying to simply query a table from a database:</p>
  
  <pre><code>SELECT * FROM operation.fs.ten_q_score;
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>SQL Error [0A000]: ERROR: cross-database references are not implemented: "operation.fs.ten_q_score"¶  Position: 15
  </code></pre>
  
  <p>I have looked at the dblink, but do not even understand how to install something like dblink (even after looking at the actual documentation). </p>
  
  <p>Any guidance is much appreciated!</p>
