pgbench-seed-6.patch (text/x-diff) patch

Here is a rebase, plus some more changes:

I have improved the error message to tell from where the value was 
provided.

I have removed the test to the exact values produced from the expression 
test run.

I have added a test which run from the same seed value several times
and checks that the output values are the same.
