I have been using PostgreSQL and XFS file systems on SGI's for many
years, and PostgreSQL is fast. Dumping and loading 100GB of table
files takes less than one day elapsed (provided there is no other
activity on that database -- large amounts of transactional activity
will slow things down). I always turn off fsync. Most of my experience has
been with 6.5.3, although I've been using 7.1 and I don't see much
of a difference in performance.
I don't know if the Linux version of XFS is substantially different
than the SGI version, but XFS is a wonderful filesystem to use and
administer (at least on SGI's).
