Allowinherited tables to inherit index
 

What is the spec for this?  

Do you mean that inheriting tables should share a single index with their
ancestors, or that each descendant should get a separate index on the
same pattern as its ancestors'?  

With the former, the inherited index could be used to enforce a primary
key over a whole inheritance hierarchy, and would presumable make it
easier to implement RI against an inheritance hierarchy.  Is this what
you have in mind?
