Postgres Combine Summed Values from 2 Queries / Tables into Single Row
Looks like I can use CROSS JOIN
SELECT recorded_minutes, recorded_hours, budgeted_minutes, budgeted_hours
FROM
    (SELECT 
        SUM(minutes) as recorded_minutes,
        SUM(hours) as recorded_hours
    FROM recorded_time
    WHERE
        project_id = 1) rt
CROSS JOIN
    (SELECT 
        SUM(minutes) as budgeted_minutes,
        SUM(hours) as budgeted_hours
    FROM budgeted_time
    WHERE
        project_id = 1) bt
