AFAIK, PostGIS cannot print neither calculate transformation matrices.

Hi all!
I've found that values of transformation matrix reported by
v.transform are erroneous after using this values in ST_Affine (a
PostGIS's function).
The values that seems to be erroneous are x_offset and y_offset. The
rotation values seems to are fine.
The transformed elements are ok (it i
