Shared memory in NetBSD is just an interface to mmap'd pages, so it can
be swapped to disk. But I assume your swap is not on NFS....

A ktrace would be helpful. Also, it would be helpful if you tried doing
an initdb to a directory on the filer to see if you can even create a
database cluster, and tried doing that or rsyncing and accessing your
data over NFS with a NetBSD system as the NFS server.
