title: ERROR: function regexp_like(character varying, unknown) does not exist
body: <p>I have this <code>SQL</code> query that I'm writing using <code>Postgresql</code>.</p>
  <pre><code>select * from cdr_data 
    where REGEXP_LIKE(identifiant,'^73')
      and REGEXP_REPLACE(callednumber,'^256','') ~ '^73'
  </code></pre>
  <p>It gives me following error:</p>
  <pre><code>[Err] ERROR:  function regexp_like(character varying, unknown) does not exist
  LINE 2: and  regexp_like(identifiant,'^73')
  </code></pre>
  <p>I have tried replace with <code>REGEXP_LIKE</code> with <code>LIKE</code> and <code>REGEXP_MATCHES</code> but they don't work.</p>
  <p>What could be the problem?</p>
