I do not recommend changing an existing table column name.

To change the column name you would have to drop the foreign key, drop the primary key constraint, not to mention all indexes as they are built on the primary key. You would then change the column name and rebuild everything you dropped.

Question, why do you need to change the column name and access to the column can change the name using alias?
