1. Add a trigger for DDL events and then update a publication: ```sql BEGIN; CREATE TABLE public.evt_pub_t1 (id int PRIMARY KEY); CREATE TABLE public.evt_pub_t2 (id int PRIMARY KEY); CREATE PUBLICATION evt_pub_repro FOR TABLE public.evt_pub_t1; CREATE OR REPLACE FUNCTION public.evt_dbg_fn() RETURNS event_trigger LANGUAGE plpgsql AS $$ DECLARE cmd record; BEGIN RAISE NOTICE 'ddl_command_end fired: tag=%', tg_tag; FOR cmd IN SELECT * FROM pg_event_trigger_ddl_commands() LOOP RAISE NOTICE 'cmd: type=% identity=%', cmd.object_type, cmd.object_identity; END LOOP; END $$; CREATE EVENT TRIGGER evt_dbg_trg ON ddl_command_end EXECUTE FUNCTION public.evt_dbg_fn(); -- control: should fire notice CREATE TABLE public.evt_control (id int PRIMARY KEY); -- test case ALTER PUBLICATION evt_pub_repro ADD TABLE public.evt_pub_t2; ROLLBACK; ``` What happens: `ALTER PUBLICATION ... ADD TABLE ...` succeeds, but no `ddl_command_end` notice appears for it Expected: `ALTER PUBLICATION` also fires the event trigger and appears in `pg_event_trigger_ddl_commands()`
