When you have a vertical wood post (or column) on masonry or concrete, and that concrete/masonry itself rests on the earth, then that post must be pressure treated. You don't need to use pressure treated wood if an impervious moisture barrier and a 1-inch metal or masonry pedestal separate the post from the earth by a total of 6 inches in ...
