Carbon already support RENAME TABLE, if carbon can support RENAME column
name and data type, it's better.

Can we support like this?

ALTER TABLE table_name CHANGE [COLUMN] col_old_name col_new_name
[column_type];

column_type is optional. default is keep the same data type with old column
data type
