Hi,
I've found that postgresql92 package is listed for RHEL/CentOS/SL/OL 6
at http://www.postgresql.org/download/linux/redhat/, but now there is
also rh-postgresql94 package available for both, 6 and 7 OS versions
(also as SCL), so it may be helpful for people to know that.
Hopefully this is a good list for asking for such a change.
