title: HSQLDB and Array
body: <p>Hsqldb 2.0 documentation talk about array and report this example:</p>
  
  <pre><code>CREATE TABLE t (id INT PRIMARY KEY, scores INT ARRAY DEFAULT ARRAY[], names VARCHAR(20)
  ARRAY[10])
  </code></pre>
  
  <p>I tried it but I obtain this exception:</p>
  
  <pre><code>[Error Code: -5581, SQL State: 42581]  unexpected token: ARRAY
  </code></pre>
  
  <p>How can I enable it?</p>
