In Red Hat's own packaging, you should temporarily install the
postgresql-upgrade RPM, which contains pg_upgrade as well as a copy
of the previous-generation postmaster. If you use Devrim's packages,
I think he more nearly follows the Debian approach. Either way, if
a packager has failed to allow pg_upgrade to be usable within his
package set(s), it's a packaging error that you should complain
about.
