I don't know if that's true, and I definitely don't know if they all
handle corner cases identically. I think this patch is an exercise in
guessing at what the SQL committee will eventually do, and as such, we
should avoid like the plague making any guesses that carry significant
risk of being semantically incompatible with what they eventually do.
The risk/reward ratio isn't good enough.
