title: How can I run an ad-hoc script in PostgreSQL?
body: <p>I'm trying to run this in PostgreSQL 9.2:</p>
  <pre><code>RAISE NOTICE 'Hello, World!';
  </code></pre>
  <p>And the server says:</p>
  <pre class="lang-none prettyprint-override"><code>Error : ERROR:  syntax error at or near &quot;RAISE&quot;
  LINE 1: RAISE NOTICE 'Hello, World!'
              ^
  </code></pre>
  <p>Why?</p>
