According to this, column privilege descriptors are created automatically

privilege, can I JUST check column level privilege?

While possible, for performance reasons it would probably be unwise. Needs checking.

We can possibly infer their existence according to the table level privileges in certain cases. But it's not clear to me how that will work when we change the table level privileges, nor how it works with revoked privileges. Do we have any provision for negative privileges? If not, do we need them?
