Hi,

I'm trying to do something like this:

BEGIN;

CREATE TABLE A
(
idA serial not null primary key,
someColumn text
);

CREATE TABLE B
(
someData text
) INHERITS(A);

CREATE TABLE C
(
idC serial not null primary key,
anotherColumn text
);

CREATE TABLE BC(
idB int4,
idC int4,
 FOREIGN KEY (idB) REFERENCES B(idA),
 FOREIGN KEY (idC) REFERENCES C(idC)
);

COMMIT;

But When it is going to create the table BC, it gives an error:

ERROR:  there is no unique constraint matching given keys for referenced table "b"

My question is: Shouldn't it get Table A primary key and create the foreign key?

Thx
Luiz Eduardo
