An ALTER TABLE cannot be cancelled. We do not do the work until you say commit. Once you say commit, you are committed to finishing the
operation. If a system failure of some form occurs (say a database restart), the ALTER TABLE will be reinstantiated and run to completion.
Rather than log everything so we can go back, we make sure we always go forward and finish the job.
