I'm working on a project which needs to satisfy some legal

Is there any way to disallow self changing of password by ordinary

If you check http://www.postgresql.org/docs/8.2/static/client-
authentication.html
you'll see a bunch of different ways to authenticate users. Most of
them are
external to the database, so don't allow changing the password from
within
the database.
One of those should satisfy your needs - PAM in particular allows you to
plugin a huge variety of backends to provide a lot of different
behaviors.
