this migration was originally written with a backfill, but the
submissions table was large enough that the backfill was very slow. so
we changed to create the column with a default, taking advantage of
PG11+ ability to do this quickly rather than lock the table. But some
operators have not upgraded postgres versions yet, so let's support both
methods for now, while we work out a clear upgrade timeline.
