有时,在批量数据加载时,建议临时删除表上的约束和索引.但是当我这样做时,我遇到了一些依赖问题.我的简化示例:

CREATE TABLE public.t_place_type
(
  id serial NOT NULL,
  c_name character varying(100),
  CONSTRAINT pk_t_place_type PRIMARY KEY (id)
);

CREATE TABLE public.t_place
(
  id serial NOT NULL,
  c_name character varying(50),
  id_place_type integer,
  CONSTRAINT pk_t_place PRIMARY KEY (id),
  CONSTRAINT fk_t_place_t_place_type FOREIGN KEY (id_place_type)
      REFERENCES public.t_place_type (id) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION
);

CREATE OR REPLACE VIEW public.v_place AS 
 SELECT p.id,
    p.c_name,
    pt.c_name AS c_place_type
   FROM t_place p
     LEFT JOIN t_place_type pt ON pt.id = p.id_place_type
  GROUP BY …
