> See the example where t3.id is INT4 and t4.id INT8. In this case, t3.id and t4.id are different but compatible to each other. 
> In this case, current planner handles the expression incorrectly. As a result, the cross join plan is generated. We should fix it.
> {code}
> select * from table3 t3 join table4 t4 on t3.id = t4.id;
> {code}
