A piecewise constant function is usually called  "step function".
I am not sure if the step function(s) used in a Riemann sum have
a particular name.  

Maybe istead of \psSum you could use \psRiemannSum, it is still
not a sum but it reflects the main application of such functions,

For what is worth,
