Hmm, in that case the penalty probably comes from pushing WAL data out
to disk synchronously. It might be worth playing with wal_sync_method
and/or raising wal_buffers.
The trouble with turning fsync off is that a system crash midway through
the import might leave you with a corrupt database. If you're willing
to start over from initdb then okay, but if you are importing into a
database that already contains valuable data, I wouldn't recommend it.
