So based on our discussion of last week my understanding is that as long as
these people are content to release the code under the same license then
these statements don't change anything since they're included in the
Postgresql global development group anyways.

Does anyone have contacts to the other people listed?  Ideally we can
get them to send the list an email stating their copyright notice can be
removed.

Below is a summary of each item:
--------------------------------

I received permission from Andrew Yu to remove a copyright he had on
another file in 2007:

       http://archives.postgresql.org/pgsql-hackers/2007-03/msg01528.php

I have emailed him to get approval to remove this mention also.

---------------------------------------------------------------------------

The intagg copyright is on a _Makefile_:

       # Makefile for integer aggregator
       # Copyright (C) 2001 Digital Music Network.
       # by Mark L. Woodward
       # $PostgreSQL: pgsql/contrib/intagg/Makefile,v 1.10 2008/11/14
19:58:45 tgl Exp $

Seems we either have to contact the author or rewrite the file.

---------------------------------------------------------------------------

The rint.c file is again tiny:

 * rint.c
 *    rint() implementation
 *
 * Copyright (c) 1999, repas AEG Automation GmbH

Perhaps that just needs to be rewritten.

---------------------------------------------------------------------------

The ISN copyright looks like this:

        * Copyright (c) 2004-2006, Germ<E1>n M<E9>ndez Bravo (Kronuz)
        * Portions Copyright (c) 1996-2010, PostgreSQL Global Development
Group

Interestingly, he mentions himself and PGDG both in the copyright, which
makese this less of an issue.  Looking at the ISN code, it appears he
was the creator of the original file:

       revision 1.1
       date: 2006/09/09 04:07:52;  author: tgl;  state: Exp;
       Add contrib/isn module for ISBN/ISSN/EAN13/etc product numbers, and
       remove the old isbn_issn module which is about to be obsoleted by
EAN13.
       contrib/isn is by Germ<E1>n M<E9>ndez Bravo.  Our thanks to Garrett
A.
       Wollman for having written the original isbn_issn module.

and he asked about his copyright mention as part of the patch
discussion:

       http://archives.postgresql.org/pgsql-hackers/2006-09/msg00794.php

I never saw the issue actually addressed and the copyright line was
committed.
Do people think it is acceptable?

The UCS_to_GB18030.pl is a Perl script with this at the top:
