Re: pgbench - add pseudo-random permutation function

I updated the patch. And also I added some explanations and simple 
examples in the modular_multiply function.

Fabian-san,

To make easily understanding, I think it is a good idea to add a brief 
explanation of outline the pseudorandom_perm function and bijective 
functions/transformations. What do you think about?

Best regards,
