Postgres definitely doesn't use RPC, you don't need it for that. The 2 main things that you need portmap for are: 1. NIS (aka YP, yellow pages) 2. NFS /etc/init.d/mountnfs.sh checks if you have any NFS mounts setup in /etc/fstab. If you have, it starts portmap - because it is needed for the mount. If nothing else is starting portmap, this is it. Mike.
