What if you compared the "widths" of your two geometries by looking at
the difference in the xmax and xmin? You can then compute the relative
size ratio along the x-axis to be used in the second parameter of
ST_Scale(geometry g, int x, int y, int z). Do the same for the y and z
axis.

ST_Scale(geometry, float8, float8) - this function does the job but the
releative size needs to be known as a float8.
Is there a method of establishing the float8 by comparing the relative
size of the two geometries. (I've looked at St_Difference but it just
returns a geometry).
