Licence name change

It's clear a number of people on this list saw my monster commits last
night, changing our licence name from BSD to PostgreSQL, but aren't
aware of the reason for that change.

For background info, please see

In a nutshell - the licence itself hasn't changed, just the name we
use to refer to it. The change makes no difference to anyone except
possibly those involved in any form of marketing!!
