    Description

      Currently we simply delete the column stats after renaming a database, table, or partition since there was not an easy way in HMS to update the DB_NAME, TABLE_NAME and PARTITION_NAME in TAB_COL_STATS and PART_COL_STATS. With the removal of these redundant columns in these tables (HIVE-11786), we will still keep column stats in the operation which is not to change a column name or type.
