What is the restore actually doing at the moment? (Look in
pg_stat_activity)
For such a large DB I'd think you'd really need to increase
shared_buffers, checkpoint_segments, and maintenance_work_mem well
beyond their default values ... did you do that before starting to
restore? (Actually I think you could probably do the latter two
on-the-fly without disturbing the restore, so that might be something
to try before giving up and starting over.)
