Subject: How to get a notification

Hi, ALL,
In my code I'm running following:
queries.push_back( L"CREATE FUNCTION
__watch_schema_changes() RETURNS event_trigger LANGUAGE plpgsql AS $$
BEGIN NOTIFY tg_tag; END; $$;" );
queries.push_back( L"CREATE EVENT TRIGGER
schema_change_notify ON ddl_command_end WHEN TAG IN(\'CREATE TABLE\',
\'ALTER TABLE\', \'DROP TABLE\', \'CREATE INDEX\', \'DROP INDEX\')
EXECUTE PROCEDURE __watch_schema_changes();" );
My questions are:
1 Is there a better way to get notification about CREATE/ALTER/DROP TABLE?
2. How do I receive notification abut the event with the object name?
Thank you.
