determine the curval() of a view

Hi,

I am working with a view that has a "_INSERT" rule.  I'm wondering if there is 
a way to determine what the curval() of the PK (serial type) after an insert 
occurs.  

Given the name of the view I'd like to determine the sequence associated with 
the view's PK.  Actually, I wonder if it is even possible to determine the PK 
from the view name.  I'm guessing that it might be possible because the view 
must be associated with a table/s.  And they will have PK's.

Any hints will be very helpful.
