Comment(by pracine):

 If I just negate the scaley of the raster then I get a raster correctly
 aligned :

 {{{
 SELECT ST_Asbinary((gv).geom) geom, (gv).val
 FROM (SELECT ST_PixelAsPolygons(
                ST_AsRaster(
                            ST_Buffer(ST_SetSRID(ST_MakePoint(2, 1), 0),
 1.3),
                            ST_MakeEmptyRaster(4, 4, 0, 0, 1, -1, 0, 0, 0)
                           )
              ) gv
      ) foo
 }}}
