Re: 8.3RC2 vs 8.2.6 testing results

Pavel:

thanks for your feedback. To me plans generated by 8.2 and 8.3 are
equal and only differ by execution times. (I don't know, maybe email
wrap'ed lines, so I've attached plans to my message). Also, I confirm
that that parameter was increased (to 100) before the ran tests.
