Comment (by jorgearevalo):

 Hello,

 Basically, the problem is the tiles of the second image (the elephant)
 don't have the same size. The image is 299x439 px and the tiles are 40x20
 px. The GDAL driver still can't work properly with irregularly tiled
 raster coverages. But good news are I'm currently working on it, to add
 complete support for all kinds of raster arrangements defined in
 http://trac.osgeo.org/postgis/wiki/WKTRaster/Documentation01 (section
 3.1.2).

 At same time, I'm working on fixing the errors on functions like
 ST_DumpAsPolygons, to finish the tasks for Objective 0.1.6e.

 I'm very sorry for these problems. And many thanks for the testing job!
