Misunderstanding, sorry: I meant the better performance of
the 8.4 *server* and would like to update libpq therefore as
well. The question was, what however happens if I then need
to connect to older (8.2) servers using the newer (8.4) libpq
libraries.

May I, the other way round, assume from your reply that
there is neither a disadvantage nor a compatibility issue
when I stick to libpq 8.2 (not upgrading to 8.4) but update
the *server* to 8.4?
