The 8.2 client library will speak just fine to 8.4 server. The client
utilities (such as psql, pg_dump, etc) should match version numbers
for best compatibility.
What I'd do is first upgrade the server to 8.4, then the client. Or
upgrade the client while you're doing your dump/restore to upgrade
from 8.2 to 8.4.
