Description:
Server crashes if incorrect WHERE condition for a column used as definition for a JOIN is provided.

How to repeat:
SELECT table1.id
FROM table1
LEFT JOIN table2
USING (id)
WHERE table2.id IS NULL

Suggested fix:
Because the SQL statement is wrong, the parser should throw an error, so that the server doesn't crash.
