Well there's your problem:) The the new(9.4) data directory needs to
have been created by 9.4. Right now pg_upgrade thinks it is doing a 9.0
to 9.0 upgrade. The error message is not telling you it is at 9.4 but at
a Postgres other then 9.4.
Use the 9.4 initdb or pg_ctl init to create a new data directory that
pg_upgrade can move the 9.0 data to.
