Is it rejected for VALUES, even if those VALUES are named ?
This one should work, doesn't it ?
insert into t1 (c1, c2) by name select * from (Values (1,2)) x(c2, c1)

And is missing a test for select *, right ?
create table a(a int, b int, c int);
create table b(b int, c int, a int);
insert into a by name select * from b;
