title: How do i get a bounding polygon around points?
body: <p>I have a table with thousands of addresses as points. </p>
  
  <p>Is there a function in postgis that will allow me to get a bounding polygon around these points and return it as a polygon?</p>
  
  <p><strong>update</strong> I am looking for a more complex polygon than just a bounding rectangle</p>
