Re: DAFS?

*shrugs*, I use shared attached storage.  Routing this stuff through
nscd (which is what most of those user-space apps do) would be silly.

You'd still need a filesystem on top of it for postgres, which negates
the whole issue.  You'd might was well just use a SAN then.  Netapp
announced that they're adding an option for this, the original poster
might want to look into that.
