title: How to specify ONLY 'scale' for 'numeric' type in PostgreSQL?
body: <p>In PostgreSQL in order to specify 'scale' for a 'numeric' type I must specify it like this:</p>
  <blockquote>
  <p>NUMERIC(<em>precision</em>, <em>scale</em>)</p>
  </blockquote>
  <p>So I must specify precision as well. PostgreSQL docs say that:</p>
  <blockquote>
  <p>Note: The maximum allowed precision when explicitly specified in the
  type declaration is 1000;</p>
  </blockquote>
  <p>Is there a way to specify only 'scale' and leave 'precision' as default?</p>
