If there is information which I have not provided, but which would be
usefull, or if the bug can not be reproduced, please let me know.

 PostgreSQL 7.0.3 on i686-pc-linux-gnu, compiled by gcc 2.95.3
- --installed as a SuSE 7.2 package

The following code is run:

CREATE TABLE k(d CHAR(1),e CHAR(1));
CREATE TABLE l(d CHAR(1),f CHAR(1));
CREATE TABLE m(d CHAR(1),g CHAR(1));
INSERT INTO k VALUES ('d','e');
INSERT INTO l VALUES ('d','f');
INSERT INTO m VALUES ('d','g');
SELECT * FROM k NATURAL JOIN l NATURAL JOIN m;

Here is what happens:
