Wouldn't you be describing a Linux-specific issue, though?  And possibly 

It's hard to reconcile this with the real-world performance of 
PostgreSQL on NFS, which is happening all over the place.  Most notably, 
Joe Conway's 20,000 txn/sec.

I *do* think it's an accurate statement that if you're going to use 
Postgres, or any other OLTP database, on NFS you'd better have access to 
a NAS expert.  But to say that it's a bad idea even if you have expert 
help is probably going to far.
