Comment(by pracine):

 It is not explicit in the spec but you never want to do that... You would
 lose most of your raster. What you might want to do however it to realign
 a raster so it matches the grid of a second one. To do that you pass the
 upper left corner x and y of the second to ST_Resample and you just snap
 the upper left corner of the first to the grid defined by this x and y and
 the provided pixelsize.

 In other words x and y are not really the upperleft corner of the second
 raster but just the upper left corner of any pixel of the grid you want to
 snap to.
