You should increase maintenance_work_mem as much as you can.
full_page_writes, archive_mode and auto_vacuum should be disable
during restore. Increase checkpoint_segments (for example to 64) and
set wal_buffers to 16MB. 8.4 introduced parallel restore (pg_restore
option -j <num jobs>).

Maybe you can't do anything mentioned above because it is not possible
to restart server (you can change maintenance_work_mem via PGOPTIONS)
or there is a single table to import (-j is not aplicable) -- try to
drop indexes and recreate them after import.
