well deployment is the same as for deploying it to plain old direct
attached storage - so all the docs available on www.postgresql.org are
more or less valid for this.

all of those are used - however NFS is quite often discouraged due to
various reliability issues (mostly on the client side) and operational
complexity that caused issues in the past. ISCSI and Fiberchannel
deployments (both on netapp based storage and others) have worked very
well for me.

that is an extremely broad question - in doubt it is always "the
application the customer uses".

not sure what a business issue would be here - but as for technical
issues postgresql is comparable to the demands of other (commercial)
databases in that regard. I personally found general tuning guidelines
for storage arrays that got written for oracle to be pretty well
suitable(within limits obviously) for postgresql too.

it's the customer that counts :)

not sure what the question here is - maybe you can explain that in more
detail?
