How to get a notification

[Igor Korot <ikorot01@xxxxxxxxx>]

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.
