This is about post_type pages
wp_list_pages I can list all the pages in hierarchy, but i want to implement this functionality quite different,
I want to display the previous and next pages in the page-hierarchy like
on page p3, p2 and p4 will be the previous and next pages respectively,
but this breaks for page p4 it shows previous page as p3 but no next page but i want to show next page as p5, how to achieve this kind of pagination!!!!!!!!!!!!
