check_result option to be flexible on column name/order

[machow]

Minimal example:

CREATE TABLE simple ( id INTEGER)
INSERT INTO simple (1)

Pass both SELECT id FROM simple and SELECT id as id2 FROM simple.

Realistic Example:

For example, both should pass:

SELECT 
    EXTRACT(MONTH FROM start_time) AS month, 
    COUNT(*) 
FROM trips 
GROUP BY month;

SELECT 
    EXTRACT(MONTH FROM start_time) AS month, 
    COUNT(*) as ttl
FROM trips 
GROUP BY month;
