I guess you could trick the binary choice then force another server
choice :
pg_dump --cluster 8.4/main -p <port of 8.3> ...
But I'd simply go with:
/usr/lib/postgresql/8.4/bin/pg_dump <options to target 8.3>
For people unaware of debian way of supporting more than one major
version and cluster, all PostgreSQL user binaries in /usr/bin are a link
to their pg_wrapper, which support the --cluster 8.X/clustername option
and will choose the right versionned binary and port number etc.
