So, I'm working around it by creating the new columns with the default
value that I want populated, and then resetting the default. This works,
but it doesn't feel like a best practice.

Can someone recommend a better way to say, consolidate 3 columns down to
2 and conditionally move contents around to the new columns, inside of a
transaction involving ALTER TABLE calls?

I'm just wondering if there is a better solution than what I've done.
