I see. The problem is that there isn't a way to override the check from SQL. Iceberg does allow you to make incompatible changes if you decide to "force" the change. But the SQL API doesn't have a way to do that an will always fail. Looks like Postgres supports this by immediately checking the table to see if there are any null values. We should be able to use a metadata check to do the same, assuming that the column's metadata collection is not set to `none`. -- This is an automated message from the Apache Git Service.
