upgrading postgresql from 9.0.4

view story

https://bbs.archlinux.org – I am trying to upgrade postgresql from 9.0.4 to 9.2.3 using the directions from the wiki (postgresql page, under "upgrading"), due to systemd causing my connections to be refused on my socket for 9.0.4...# pacman -S postgresql-old-upgrade postgresql-libs :: postgresql-libs is in IgnorePkg/IgnoreGroup. Install anyway? Y/n resolving dependencies... looking for inter-conflicts... :: postgresql-libs and postgresql are in conflict (postgresql-client). Remove postgresql? y/NIf pacman wants to remove my old postgresql binaries, then how is pg_upgrade supposed to work when I need to feed it (HowTos)
