> Since the Iceberg table migration will intentionally not rewrite the data
> files, the migrated table will end up with data files that do not contain the
> Iceberg field IDs necessary for safe, reliable schema evolution. For this
> purpose, we should disallow the REPLACE COLUMNS and CHANGE COLUMN commands
> for these migrated Iceberg tables. ADD COLUMNS are still permitted.
