The above copyright mentions have no actual BSD copyright text, so what
do we do?  If we assume they are BSD copyrights that match our own, we
perhaps don't have a problem.  If not, we do have a problem.

The one that is a more serious issue is in
/pgtop/contrib/pgcrypto/blf.*, where the BSD advertising clause is in
the copyright, and the author has updated the copyright:

 *    must display the following acknowledgement:
 *      This product includes software developed by Niels Provos.

I will try to contact all the authors to get permission to clean this
up.
