The specific problem is that there might be a server behavioral change
that pg_dump has to compensate for.  (Obviously this is not very
desirable, but we've had to make such changes in minor releases in the
past.)  8.2.0 pg_dump cannot know the future, so it has to err on the
side of caution and complain when it sees a newer server version.
