You may even find that some DROP events are not returned by pg_event_trigger_ddl_commands. I suggest you stick to pg_event_trigger_dropped_objects() instead (for which you need sql_drop). -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
