Thanks for taking a look. I figured the way I wrote it makes it easier
to move the code around or insert other code in the future and doesn't
make it so tightly coupled.
Anyway, I figured out how to take account of generation expressions with
different column orders. I used the same approach that we use for check
constraints. The attached patch is good to go from my perspective.
