I don't like it - "check trigger" is simple - and consistent

this is good idea - and I like it
CHECK TRIGGER ALL ON TABLE X
there are possible some combination like CHECK TRIGGER ALL IN SCHEMA ...;
and similar. But I am not sure, if this is necessary - for some more
complex usage developer can use a direct PL check function.

this should not be nice from language view, but it doesn't need new keywords
pattern FOR ROLE, IN SCHEMA are used
ALTER DEFAULT PRIVILEGES FOR ROLE
but OWNED BY is used too (SeqOptElem:)
I agree so OWNED BY sounds better (can be changed)

it is ok too
