Hi
I found another bug
create view xx as WITH recursive destinations (departure, arrival, connections, cost, itinerary) AS
(SELECT f.departure, f.arrival, 1, price,
CAST(f.departure || f.arrival AS VARCHAR(2000))
FROM flights f
WHERE f.departure = 'New York'
UNION ALL
SELECT r.departure, b.arrival, r.connections + 1 ,
r.cost + b.price, CAST(r.itinerary || b.arrival AS VARCHAR(2000))
FROM destinations r, flights b
WHERE r.arrival = b.departure)
CYCLE arrival SET cyclic_data TO '1' DEFAULT '0' using path
SELECT departure, arrival, itinerary, cyclic_data
FROM destinations ;
(SELECT f.departure, f.arrival, 1, price,
CAST(f.departure || f.arrival AS VARCHAR(2000))
FROM flights f
WHERE f.departure = 'New York'
UNION ALL
SELECT r.departure, b.arrival, r.connections + 1 ,
r.cost + b.price, CAST(r.itinerary || b.arrival AS VARCHAR(2000))
FROM destinations r, flights b
WHERE r.arrival = b.departure)
CYCLE arrival SET cyclic_data TO '1' DEFAULT '0' using path
SELECT departure, arrival, itinerary, cyclic_data
FROM destinations ;
postgres=# select * from xx;
ERROR: attribute number 6 exceeds number of columns 5
