FULL OUTER JOIN causes confusion

[petdance]

select *
from users u
full outer join departments d on u.deptid = d.id

gets transformed into

SELECT
    *
FROM
    users u FULL
    OUTER JOIN departments d ON u.deptid = d.id

when it should get transformed into

SELECT
    *
FROM
    users u
    FULL OUTER JOIN departments d ON u.deptid = d.id

sleek works correctly if that's a LEFT OUTER JOIN.

SELECT
    *
FROM
    users u
    LEFT OUTER JOIN departments d ON u.deptid = d.id

The table aliases don't seem to affect it one way or the other.

SELECT
    *
FROM
    users FULL
    OUTER JOIN departments ON users.deptid = departments.id
