Copyright notices

Say Bruce, I notice that a lot of the files under src/bin still have

# Copyright (c) 1994, Regents of the University of California

and have never had a Postgres group copyright added to them. I updated
createdb just now to

# Portions Copyright (c) 1996-2001, PostgreSQL Global Development Group
# Portions Copyright (c) 1994, Regents of the University of California

but shouldn't they all look like this?

They should all look like this. I will do it now.
