Re: EXCEPT

The note about parentheses is not quite accurate for 10.4. Parentheses can be used in some situations, but as of 10.4.8, attempting to use parentheses around a compound select that is inside an IN() expression (for example) will not be parsed:

This does not work:

select * from people where id in (
    (select id from people where name = 'foo')
    union
    (select id from people where name = 'bar'))
