Comment (by Claude Paroz):
The temporary solution is a classic three-step migration:
1. Create a new column with the desired type.
2. Copy values from the legacy column to the new column with a data
migration.
3. Delete the legacy column (and maybe rename the new column if you want
to get back to the initial column name).
Similar to #28809.
