Not quite like that.  Look into nodeAgg.c, which solves a similar problem
for the transvalues themselves with code like

           /* forget the old value, if any */
           if (!oldIsNull && !pertrans->inputtypeByVal)
               pfree(DatumGetPointer(oldVal));

Oh great, thanks for the tip!
