[pgadmin-support] Treat an updateable View as a Table in Grid editor?

[Harald Armin Massa]

I created a time-constraint table ... that is, rows have a valid-timespan (validvon - validbis, as in "valid from" - "valid until", with German intermixed)

CREATE TABLE otlabel
(
  id_label serial NOT NULL,
  id_lg integer,
  name_l text,
  letztespeicherung timestamp without time zone DEFAULT now(),
  id_pkl serial NOT NULL,
  validvon timestamp without time zone DEFAULT '-infinity'::timestamp without time zone,
  validbis timestamp without time zone DEFAULT 'infinity'::timestamp without time zone,
  id_user integer DEFAULT 0,
  quarant integer DEFAULT 0,
  CONSTRAINT otlabel_pkey PRIMARY KEY (id_pkl),
)
WITHOUT OIDS;
ALTER TABLE otlabel OWNER TO ibox;

to make it userproof, selecting, inserting, updating and deleting has to be done with a view:

CREATE OR REPLACE VIEW label AS
 SELECT otlabel.id_label, otlabel.id_lg , otlabel.name_l, otlabel.letztespeicherung
   FROM otlabel
  WHERE now() >= otlabel.validvon AND now() <= otlabel.validbis AND otlabel.quarant = get_quarant();

CREATE OR REPLACE RULE label_delete AS
    ON DELETE TO label DO INSTEAD  UPDATE otlabel SET validbis = now(), letztespeicherung = now()
  WHERE otlabel.id_label = old.id_label AND otlabel.validbis >= '9999-12-31 00:00:00'::timestamp without time zone AND otlabel.quarant = get_quarant();

CREATE OR REPLACE RULE label_insert AS
    ON INSERT TO label DO INSTEAD  INSERT INTO otlabel (id_label, id_lg, name_l, letztespeicherung, validvon, validbis, id_user, quarant)
  VALUES (new.id_label, new.id_lg, new.name_l, now(), now(), 'infinity'::timestamp without time zone, get_user(), get_quarant());

CREATE OR REPLACE RULE label_update AS
    ON UPDATE TO label DO INSTEAD ( UPDATE otlabel SET validbis = now(), letztespeicherung = now()
  WHERE otlabel.id_label = old.id_label AND otlabel.validbis >= '9999-12-31 00:00:00'::timestamp without time zone AND otlabel.quarant = get_quarant();
 INSERT INTO otlabel (id_label, id_lg, name_l, letztespeicherung, validvon, validbis, id_user, quarant)
  VALUES (new.id_label, new.id_lg, new.name_l, now(), now(), 'infinity'::timestamp without time zone, get_user(), get_quarant());
);

Now I would be VERY VERY happy if I could trick pgAdmin into allowing me to edit this view within the Grid.

Any chance now? Or only with wihslist for 1.7? Or not at all?
