Re: [WIP] Zipfian distribution in pgbench

Hello, Fabien

I am attaching patch v7.

> Yes, I agree. a >= 10000 does not make much sense... If you want uniform you should use random(), not call random_zipfian with a = 10000. Basically it suggests that too large values of "a" should be rejected. Not sure where to put the limit, though.

I set upper bound for parameter to be equal to 1000.

Documentation have been updated, I have removed algorithms descriptions and put references to them there.
