Thank You David.

Are you saying something like below, in which we first create the function
from super user and then execute the grant? But doesn't that mean, each
time we want to create a new event trigger we have to be again dependent on
the "super user" to modify the security definer function?

CREATE OR REPLACE FUNCTION create_event_trigger_func()
RETURNS void
LANGUAGE plpgsql
SECURITY DEFINER
AS $$
BEGIN
EXECUTE 'CREATE EVENT TRIGGER event_trigger_name ON schema_name ...';
END;
$$;

GRANT EXECUTE ON FUNCTION create_event_trigger_func() TO app_user;
