To: postgres@postgres.berkeley.edu

We have version 2.01 of POSTGRES and would like to know if there is any way to
define views and rules as a hirarchical structure. For example, STUDENT and
GRADUATE_STUDENT can be defined as in the following:

i)      STUDENT-View 				ii)       STUDENT-Rule
	    |							|
	    |							|
	    | (inherits)					| (inherits)
     GRADUATE_STUDENT-View				GRADUATE_STUDENT-Rule


OR if this can be done in version 3.0.
