Comment:

 Now for the same geometry, if the raster I want to align to is:

 {{{
 SELECT ST_Asbinary((gv).geom) geom, (gv).val
 FROM (SELECT ST_PixelAsPolygons(ST_MakeEmptyRaster(4, 4, 0, 0, 1, -1, 0.2,
 0.2, 0)) gv) foo
 }}}

 then:

 {{{
 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, 0.2, 0.2,
 0)
                           )
              ) gv
      ) foo
 }}}

 is also wrongly aligned... sorry...
