Обсуждение: pg_upgrade doesn't work?

So why does the documentation tell me that I should use the pg_upgrade
command to migrate my 8.4.20 db to 9.6, but when I run the command it tells
me that the major version is different so it won't run?  Is there some kind
of issue with the location of the execution binary?

Having the exact error messgaes would be really helpful.  You're sure
that you are using the pg_upgrade from 9.6?  Note that to perform a
pg_upgrade you have to have the binaries for *both* versions installed
on to the system and then pg_upgrade will perform a copy of the data
files or will create hard-links between the old and new data
directories.

Thanks!
