No, that says that you can't remove the copyright notice from files that
have it. It doesn't say that nearby files have to have the same
license. (Compare to the GPL, which *does* say that.)

The bottom line here is that you cannot relicense code you didn't write;
this is generally true no matter what license it is distributed under.
You can take some Postgres pieces and use them in a project with a
different overall license, but those pieces are still under BSD license.
