title: ST_PointN to get Points from Geometry Column
body: <p>I have a Shapefile from which I am extracting Geometry column and storing it into Table.
  This is sample data stored in Geometry column which has 432 points.</p>

  <p>Now I want to extract each and Every point i.e. 432 points from the Geometry column and store it into another table. For that I am using <code>ST_PointN</code> column but it only gives me 1 point at a time. <code>ST_NumPoint</code> will give me 432 number but not all the points.</p>
  
  <p>How do I extract each and every point from Geometry column and store it into DB?</p>
  
  <p>Cheers,</p>
