I'm trying to use pg_upgrade to upgrade from 9.3 to 9.4 on CentOS 6 with packages from Postgres' yum repo.
I've revered to vanlla ph_hda.conf on 9.3, and ran initdb on 9.4. I don't get very far however, I get the following error, and Google doesn't seem to help.
-bash-4.1$ /usr/pgsql-9.4/bin/pg_upgrade --jobs 4 \
> --old-datadir "/var/lib/pgsql/9.3/data" \
> --new-datadir "/var/lib/pgsql/9.4/data" \
> --old-bindir "/usr/pgsql-9.3/bin" \
> --new-bindir "/usr/pgsql-9.4/bin"
