SELECT t1.relname,a1.attname,t2.relname from pg_class t1,pg_attribute a1,pg_class t2,pg_attribute a2 where a1.attrelid=t1.oid and t1.relkind='r'and a1.attnum>0 and a2.attrelid=t2.oid and t2.relkind='r' and a2.attnum>0 and t1.relname<t2.relname and a1.attname = a2.attname and a1.attisdropped=false and a2.attisdropped=false and t1.relname != t2.relname; Why?
