> Currently the finest grain of privilege is at the table/view level. This leads to the
unwieldy scenario where a different view has to be created for each combination of columns
that need to be restricted. With column level privileges this would not be required.
> In the policy file column privileges might potentially look like:
> server=server1->db=default->table=employees->column=salary->action=select
