Just out of curiosity, why use a cursor at all then?  But anyway, you
might want to consider running a custom build with a higher setting for
tuple_fraction for OPT_FAST_PLAN (look into planner.c).  I've
occasionally thought about exposing that as a GUC parameter, but
never gotten motivated to do it.
