Fix up JOIN .. USING with domains
The attached fixes select_common_type() to support the below case:create table t1( c1 int);create domain dom_c1 int;create table t2(c1 dom_c1);select * from t1 join t2 using( c1 );I didn't see a need for maintaining the domain as the preferred type. Asimple getBaseType() call on all elements of the list seems to beenough.--Rod Taylor <rbt@rbt.ca>
