title: SImple UPDATE statement freezing
body: <p>Trying to perform a simple UPDATE statement in psql:</p>
  
  <pre><code>username=&gt; UPDATE table SET some_column = 'something' WHERE some_column = '';
  </code></pre>
  
  <p>returns:</p>
  
  <pre><code>username'&gt;
  </code></pre>
  
  <p>And stays there with a flashing cursor.</p>
  
  <p>I can return the details from the table:</p>
  
  <pre><code>username=&gt; SELECT name, some_column FROM table WHERE some_column = '';
  </code></pre>
  
  <p>Something wrong with my syntax? Am I missing a step? Is there troubleshooting step to be taken?</p>
