Yeah, as it doesn't cause any trouble now, I don't bother to re-open it.
Btw, another bad to reply on the optimization rule to produce correct
constraints is the extra cost introduced by re-constructing the whole query
plan tree, and the re-inferring of constraints in `Filter`. Instead of this,
inferring the correct constraints in one pass should be more efficient.
