PostgreSQL 禁止/啓用所有觸發器

項目中需要對觸發器進行批量禁止、啓用操作，方法如下。

創建方法/函數/過程

/* Enable/disable all the triggers in database */
CREATE OR REPLACE FUNCTION fn_triggerall(DoEnable boolean) RETURNS integer AS 
$BODY$
DECLARE
mytables RECORD;
BEGIN
  FOR mytables IN SELECT relname FROM pg_class WHERE relhastriggers is true AND NOT relname LIKE 'pg_%'
  LOOP
    IF DoEnable THEN
      EXECUTE 'ALTER TABLE ' || mytables.relname || ' ENABLE TRIGGER ALL';
    ELSE
      EXECUTE 'ALTER TABLE ' || mytables.relname || ' DISABLE TRIGGER ALL';
    END IF;  
  END LOOP;

  RETURN 1;

END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;

啓用觸發器

select fn_triggerall(true);

禁用觸發器

select fn_triggerall(false);
