The upstream can think whatever they want to, it is not the BSD license.

This is the BSD license, as defined by the OSI, the Regents of the
University of California, and Fedora:


That is NOT the license used by PostgreSQL. The intent of the license
used by PostgreSQL is similar, but it is not identical. Notably, the BSD
license says that the name of the copyright holders/contributors may not
be used to "endorse or promote products derived from the software
without specific prior written permission". That clause is absent from
the PostgreSQL license.

If the PostgreSQL upstream wants to relicense to the BSD license, that
is something they can do, but we're not going to pretend it is BSD for
the sake of PR, any more than we would pretend it is the "magic flying
pony license" if they asked us to.
