Comment(by pracine):

 I personnaly don't like your extent parameter. How should I define such an
 extent? Why such an extent would be different from the extent of the
 source if the main goal of the function is mainly to retile an entire
 coverage, not to clip it? A better approch is just to let users define a
 grid by defining any arbitrary corner of the grid (gridx and gridy as in
 ST_AsRaster) and to let the function compute the right extent. Then you
 make a signature taking a reference raster from which to borrow those
 parameters.
