Reading Date's two replies, it seems that he reaches the opposite conclusion
in the later discussion-- SQL is unable to express certain relational
algebra concepts properly-- than he did originally-- Oracle's optimizer is
behaving incorrectly. I don't see him say that he has changed his mind,
though... Am I missing some subtlety here?

Chris Date surprised me by writing some more on the topic:

I actually found his follow-up here more enlightening than
his first round of thoughts. It's a good, thought-provoking
read.
