This might be tricky, since PK is often referenced by foreign keys of
other tables. So, you need to:

1. drop all the dependencies
2. rename the column
3. recreate the dependencies

You can do this using some tool like FlameRobin to generate all the
needed statements. Open table's properties page and click on Generate
Rebuild Script.
