I want to add some triggers on a subscriber only, but not on the 
origin.  Creating the triggers through an execute script and then doing 
a store trigger will leave me with the triggers on the origin as well as 
the replicas.

The only way that I can think of to do this is something like this, for 
origin=1 and subscriber=2

EXECUTE SCRIPT ( SET ID = 1, FILENAME = '/tmp/triggers.sql', EVENT NODE 
= 1,  EXECUTE ONLY ON =2);
which will create the trigger only on my replica then promptly hide it.

The following should un-hide the trigger.
STORE TRIGGER ( TABLE ID = 2, TRIGGER NAME = 'my_trigger');
Question is, will this work?  Store trigger will run across the whole 
cluster, will the store trigger command break against the origin which 
doesn't have the trigger on it?
