Subject: FOREIGN KEYs ... I think ...

I'm not sure if I'm looking at (for) the right thing or not, but if I am, 
then I'm not finding any useful examples :(

I have two tables, simplified as:

CREATE TABLE incident_summary (
   id serial,
   subject text,
   status boolean
);

CREATE TABLE incident_comments (
   id serial,
   incident_id int4,
   body text,
   comment_date timestamp,
   status boolean
);

Now, what I want to do is add a FOREIGN KEY (again, I think) that when 
incident_summary.status is changed (either closed, or reopened), the 
associated records in incident_comments are changed to the same state ...

It *looks* like it should be simple enough, I want 
incident_comments.status to change to incident_summary.status whenever 
incident_summary.status changes ... since I'm finding nothing searching on 
FOREIGN KEYS, I'm guessing that I'm looking at the wrong thing ...

So, what should I be searching on / reading for this one?  Pointers 
preferred, especially one with some good examples :)

Thanks ...
