I just noticed that too, and was about to raise it as a bug.
If it is intended, then it's not documented.
I noticed it while browsing gram.y, and thought it looks a bit ugly
having 2 almost identical code blocks, one for the normal case and one
for NOT VALID. The second block doesn't have a
ConstraintAttributeSpec, so won't allow any deferrable options.
Aside from the ugliness of the code, we can't just add a
ConstraintAttributeSpec to the second block, because that would
enforce an order to these options.
OTOH adding NOT VALID to ConstraintAttributeSpec is a bit invasive,
since it's used in quite a few places, including CREATE TABLE, where
NOT VALID is never allowed.
Thoughts?
