I'm showing up very late to the party here, but I like option 1 best.
I feel like the SQL standard has a pretty clear idea that NULL is how
you represent a value is unknown, which shows up in a lot of places.
Deciding that we're going to use a different sentinel value in this
one case because NULL is a confusing concept in general seems pretty
strange to me.
