Huh. I haven’t had any problems with IS DISTINCT FROM for rows, except for the 
situation in which a failure is thrown because the types vary, say between TEXT 
and CITEXT. That can drive the tester crazy, since it says something like:

    Results differ beginning at row 3:
        have: (44,Anna)
        want: (44,Anna)

But overall I think that’s okay; the tester really does want to make sure the 
type is correct.

Thanks,

David
