How does an application recognize the death of the postmaster

[Geoffrey <esoteric@xxxxxxxxxxxx>]

How do folks handle the death of the postmaster in their applications? 
Assuming the postmaster dies after an application has connected to the 
database, but before it makes a request.  What should I look for? 
Currently our application that's in development does not handle the 
situation well.  What we want to do is gracefully (as possible) shutdown 
the application.
