It's not recognised because your 9.0.1 psql client is connecting to a
8.1.4 server which doesn't use such a parameter, hence the warning
you're receiving when you run psql. This also explains why you can't
use the 2-parameter form of pg_start_backup as that wasn't introduced
until 8.4.
You need to connect to a 9.0 instance.
