Is there a way to tell in PL/PgSQL if the delete coming down the line is 
from a cascade delete?   I have a trigger, which when called will throw 
an error because the row its trying to change is now linked with an item 
which no longer exists.   The foreign key constraint fails since it was 
removed before underlaying components were.

This would also greatly speed up the trigger since it could skip any 
updates at all!   Thanks in advance.
