add_notifications.sql

--this file was generated by create_add_notifications.sql.py
--it creates triggers and functions which fire postgres notify events upon the given table actions
--these notify events can be listened to implenting a subclass of the PostgresListener in the lofar.common.postgres python module
--for the radb such a subclass has been made, which listens specifically to the notifications defined below
--RADBPGListener in module lofar.sas.resourceassignment.database.radbpglistener
--this RADBPGListener then broadcasts the event on the lofar bus.
