title: How to format booleans using psql?
body: <p>Using <code>psql</code>, I would like to format boolean values to display as <code>TRUE</code> and <code>FALSE</code> instead of <code>t</code> and <code>f</code> by default, as I find the latter difficult to distinguish from one another.</p>
  
  <p>I can change how <code>null</code> displays by setting the following in my <code>~/.psqlrc</code>:</p>
  
  <pre><code>\pset null 'Ø'
  </code></pre>
  
  <p>How can I do so for boolean values?</p>
