223,Breaking change ST_Extent returns a box3d_extent object,robe,pramsey,"I've been testing 1.4 on some  production apps for the past couple of days and ran into one breaking change.

Since our ST_Extent now returns a box3d_extent, this broke one of my custom functions that was expecting a box2d

To fix, I had to make a change to my app to accept box3d instead of box2d in the function call, but I also had to put in an auto cast 

CREATE CAST (box3d_extent AS box3d)
  WITH FUNCTION st_box3d_extent(box3d_extent)
  AS IMPLICIT;


While this is not a bug, it is something that is likely to break some applications.  So I presume we should make note of it in the release notes.",defect,closed,medium,PostGIS 1.4.1,postgis,,worksforme,boxes,
