No --- the issues are not with Postgres per se but with the reliability
of your NFS setup. On top of the not-infinite reliability of disk drive
hardware you now have to stack risk of failure of the NAS machine itself,
network problems, and misconfiguration problems (eg, ill-chosen mount
options).
The people who run Oracle over NFS successfully have usually paid top
dollar for quality NAS hardware and a network run by people who know
what they're doing. Put PG into that same environment and it will work
just as well. But put PG on a lesser-grade setup, run by not quite such
competent admins, and you're in for trouble.
