title: ON CONFLICT syntax error in Postgres 9.5.0
body: <p>In Postgres documentation <a href="http://www.postgresql.org/docs/current/static/sql-insert.html" rel="noreferrer">INSERT</a> there is an example of ON CONFLICT use:</p>
  
  <pre><code>INSERT INTO distributors (did, dname) VALUES (7, 'Redline GmbH')
  ON CONFLICT (did) DO NOTHING;
  </code></pre>
  
  <p>I try the same thing:</p>
  
  <pre><code>INSERT INTO name_map VALUES ('key_value', 'val1','val2') 
  ON CONFLICT (key_column) DO NOTHING;
  </code></pre>
  
  <p>But get ERROR:  syntax error at or near "ON".</p>
  
  <p>What am I missing?</p>
  
  <pre><code>postgres --version
  &gt; 9.5.0
  </code></pre>
