Description:
It would be nice, to support a simple rename of a single column.

Something like:

ALTER TABLE tab_name RENAME [ COLUMN ] old_col_name TO new_col_name;

At the moment there is only:

ALTER TABLE tab_name CHANGE [COLUMN] old_col_name new_col_name column_definition;

But sometimes you don't want to change the definition, you just want to change the name.

How to repeat:
See above.

Suggested fix:
Add a simple rename for columns at the parser.

Fixed in 8.0.3.

ALTER TABLE now supports easier column renaming using RENAME COLUMN
old_name TO new_name syntax. RENAME COLUMN is more convenient than
CHANGE, which requires respecifying the current column definition.
