In fact, the edit grid does show [PK] in the column header -- it reads:
heritages_id
[PK] int8
... and here's the output from pg_dump -s -t Heritages :
--
-- PostgreSQL database dump
--
SET client_encoding = 'UTF8';
SET check_function_bodies = false;
SET client_min_messages = warning;
SET search_path = public, pg_catalog;
SET default_tablespace = '';
SET default_with_oids = false;
--
-- Name: Heritages; Type: TABLE; Schema: public; Owner: postgres;
Tablespace:
--
CREATE TABLE "Heritages" (
heritage character varying(30) NOT NULL,
heritages_id bigserial NOT NULL
);
ALTER TABLE public."Heritages" OWNER TO postgres;
--
-- Name: Heritages_pkey; Type: CONSTRAINT; Schema: public; Owner: postgres;
Tabl
espace:
--
ALTER TABLE ONLY "Heritages"
ADD CONSTRAINT "Heritages_pkey" PRIMARY KEY (heritages_id);
--
-- PostgreSQL database dump complete

All the best,

Interesting. Out of interest (if you still have it), what does pg_dump
think the schema looks like? It sounds like pgAdmin is misreading the
schema somehow, causing the crash - most likely when it tries to detect
the primary key. One thought - in the edit grid, did the int8 column
have [PK] in the column header?
