title: How can we refer the .Values of helm inside this .sql command inside confimap
body: <p>Lets say I want to create a user with so and so password and these username,password are passed throught helm like</p>
  <pre><code>init.sql: | 
       create user .Values.username PASSWORD .Values.password ; 
  </code></pre>
  <p>But this is giving me an error saying you are passing a null interface
  My main motto is to not to reflect sensitive information in the sql statement.
  Could anyone help me out with this?</p>
