Is the recovery itself the bottleneck? There's a performance improvement submitted here: http://archives.postgresql.org/message-id/a778a7260810280033n43f70d36x8c437eacf9a54...@mail.gmail.com But I haven't been following the development of it closely, so you'll have to read the thread to see whether it will meet your needs or not.
