 I have a multipoint that I'd like to assign M to before ST_Collect'ing it
 with other multipoints and pushing into ST_GeometricMedian.

 I see no way to do it without complete deconstruction of geometry into
 sets of x/y coordinates and building them back with ST_MakePoint with an
 extra argument.

 It would be cool to have ST_SetM (and in other cases ST_SetZ) that will
 allow getting Z/M value for all objects in geometry from some other
 calculation/column.
