I stand corrected on this. 
Maybe it was first defined in pstricks-add (I think so), and later migrated to the main pstricks package, 
or maybe I'm totally wrong and it never was in pstricks-add.

Herbert, on that I stand my ground. The algebraic option DOES make a difference for pst-math.

Try 

\psplot{1}{2}{GAMMA(x)}

with the algebraic option set - it WORKS (so, the answer to this question is a resounding YES!).
Of course, the above will produce postscript errors if typeset without the algebraic option.
