This simplifies the process of adding the policies for the CAggs. Now, with one single sql statements all the policies can be added for a given CAgg. Similarly, all the policies can be removed or modified via single sql statement only. This also adds a new function as well as a view to show all the policies on a continuous aggregate. While adding or updating a policy it also checks if that policy is compatible with other policies on the CAgg.
