If you wish the trigger to result in some action taking place on 
another database, then there are two major methodologies available: 
 
 1.  The trigger could RAISE an event. 
 
     A LISTENing daemon would see that event, and do something in the 
     other database. 
 
 2.  The trigger could write data into a replicated table. 
 
     The replication system (possibly Slony-I?) would then copy 
     the replicable data to the other database.
