Re: Postgres & large objects

Matt,

Not really the answer that you are looking for and you may already do
this, but if it's a disk space or performance issue then I would suggest
moving the PGDATA dir (or the location if you are using locations) onto
a RAID5 disk array - means you can ramp up the space and you get the
performance gains of RAID5, not to mention the safety of a FS that
recovers from disk failure!
