The UNIQUE keyword is supported, unless there is some other feature or
behavior that you are expecting?
And, to split hairs, Postgres does support the foreign key *syntax*, but
throws it away and does nothing with it in the backend. So, I'd say it
supports foreign key syntax but does not support foreign keys ;)
