Thanks for the patch :)
Now, I get a different problem, this time with the following code
intended to materialize paths on the fly and summarize down to a
certain depth in a tree:
CREATE TABLE tree(
id INTEGER PRIMARY KEY,
parent_id INTEGER REFERENCES tree(id)
);
INSERT INTO tree
VALUES (1, NULL), (2, 1), (3,1), (4,2), (5,2), (6,2), (7,3), (8,3),
(9,4), (10,4), (11,7), (12,7), (13,7), (14, 9), (15,11), (16,11);
WITH RECURSIVE t(id, path) AS (
VALUES(1,ARRAY[NULL::integer])
UNION ALL
SELECT tree.id, t.path || tree.id
FROM tree JOIN t ON (tree.parent_id = t.id)
)
SELECT
t1.id, count(t2.*)
FROM
t t1
JOIN
t t2
ON (
t1.path[1:2] = t2.path[1:2]
AND
array_upper(t1.path,1) = 2
AND
array_upper(t2.path,1) > 2
)
GROUP BY t1.id;
ERROR: unrecognized node type: 203
Please apply the attached patch to help out with tab
completion in psql.
Cheers,
David.
