Uh, this is certainly supposed to work.  Maybe pg_controldata or
pg_resetxlog changed output format and pg_upgrade doesn't know how to
read it.

It is tested on fresh 9.2.10 to 9.4.1

I've done that migration many times.  Can you give the pg_config output for both installations, and the pg_controldata output for the 9.2.10?

Thanks,

Jeff
