Domains and Joins

-- standard setup:
create table t1( c1 int primary key, data text );
create domain dom_c1 int references t1 on delete cascade;
create table t2( c2 int primary key, c1 dom_c1, moredata text );

-- will not work with "using"
create view v1 as select t1.*, t2.moredata
from t1 join t2 using( c1 );

-- will work with "on"
create view v1 as select t1.*, t2.moredata
from t1 join t2 on t1.c1 = t2.c1;

is this right?
