   I couldn't wait, so I just tried it.
   
   Same result using `DROP` and `ADD`
   
   ```sql
   create table data.test_table (ts timestamp not null, day_of_ts date) using 
iceberg partitioned by (day_of_ts);
   alter table data.test_table SET TBLPROPERTIES ('format-version' = '2');
   refresh table data.test_table;
   alter table data.test_table DROP PARTITION FIELD day_of_ts;
   refresh table data.test_table;
   alter table data.test_table add partition field days(ts);
   refresh table data.test_table;
   alter table data.test_table drop column day_of_ts;
   refresh table data.test_table;
   select * from data.test_table;
   ```
