Yeah, that pg_dump restore time is pretty rough.
As I recall, the initial backup of our 360GB (or so) database took
about 6 hours and the restore only took about 2 hours. One nice thing
(well, in a way I guess) was that the whole thing compressed down to
under 100GB. This was on an IBM DS4600 SAN (iirc, something along those
lines) with 5 320GB FC disks in a RAID-5.
I'm not really looking forward to the day I get to pg_dump and
pg_restore the whole thing to move to 8.1. :)
Thanks,
