My bad. I'm at work at the moment and I tried it out here to rejig my
memory before posting. I do remember testing it on HEAD at home and the
create table (.., unique, unique) doesn't duplicate.
Don't worry - it's being developed on HEAD - I was just trying to get out of
figuring out how to detect an already existing index across specified
columns. It's complicated.
