Caution D'Arcy,
the FOREIGN KEY syntax that's in 6.5 is a little incomplete.
Doesn't allow match type and constraint attribute
specification (deferrability and initial deferred state).
Especially the match type is required, because in 7.0 only
MATCH FULL will be implemented, not the <unspecified>
default.
As I said in another post, the constraint attr spec isn't
possible in column constraint right now in 7.0, but we're
working on it. Should be ready in a few days.
