PCI Passthrough

Warning: unfinished (but successfull!)

I did PCI passthrough on Archlinux and Debian with the old PCI-stub method (this was pre-4.0 era). And later I did PCI passthrough on the 4.1+ kernels on Arch and Ubuntu (16.10 I think?).

This is my attempt at doing the same on Nixos.

Requirements

# The following are suggested values
# They should be set in all configs,
# so that if a secondary needs to be promoted
# it will be generating the correct WAL level
wal_level = hot_standby
archive_mode = on               # allows archiving to be done
                                # (change requires restart)
archive_command = 'cp -f %p /data/pgsql/archive/%f </dev/null'          # command to use to archive a logfile segment
max_wal_senders = 5             # max number of walsender processes
                                # (change requires restart)
