examples about does not work (

CREATE TABLE connectby_tree(keyid text, parent_keyid text, pos int);

INSERT INTO connectby_tree VALUES('row1',NULL, 0);
INSERT INTO connectby_tree VALUES('row2','row1', 0);
INSERT INTO connectby_tree VALUES('row3','row1', 0);
INSERT INTO connectby_tree VALUES('row4','row2', 1);
INSERT INTO connectby_tree VALUES('row5','row2', 0);
INSERT INTO connectby_tree VALUES('row6','row4', 0);
INSERT INTO connectby_tree VALUES('row7','row3', 0);
INSERT INTO connectby_tree VALUES('row8','row6', 0);
INSERT INTO connectby_tree VALUES('row9','row5', 0);


SELECT * FROM connectby('connectby_tree', 'keyid', 'parent_keyid', 'row2', =
0, '~')
 AS t(keyid text, parent_keyid text, level int, branch text);

You didn't install that contrib module.
http://www.postgresql.org/docs/8.3/static/contrib.html

            regards, tom lane

Please, can you put this hint to 'F29. tablefunc' chapter:
NOTICE: You need to install contrib module

thx

Well, it is here:
http://www.postgresql.org/docs/8.3/interactive/contrib.html
