Actually, no, though I had the same question for Peter when I was first
reviewing this.
XLTW_InsertIndexUnique is used when building a unique index, but this is
just a check, and more to the point, it's actually a re-check of what
we're doing in nbinsert.c where we're already using XLTW_InsertIndex.
We wouldn't want to end up returning different error messages for the
same command under the same conditions just based, which is what we'd
potentially end up doing if we used XLTW_InsertIndexUnique here.

Agreed. I'm going to play with it a bit more but barring objections,
I'll commit and back-patch Peter's patch.
Thanks!
