I need to install some Postgres9.1 libs, but "yum list" only shows 8.4 version.
How to "update" yum repo list to get 9.1 version?
My Linux version:
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.9 (Tikanga)
-
See if any 3rd-party repository has it (it's likely because rhel5.9 is a bit old for pgsql91): pkgs.org/search/postgresql– anonOct 2, 2014 at 22:51

You can use the yum repository provided by the PostgreSQL project:
rpm -hiv http://yum.postgresql.org/9.1/redhat/rhel-5-x86_64/pgdg-redhat91-9.1-5.noarch.rpm
or
rpm -hiv http://yum.postgresql.org/9.1/redhat/rhel-5-i386/pgdg-redhat91-9.1-5.noarch.rpm
That will add their repository for you. See this document for more information.
PGDG publishes RHEL 5 packages; see http://yum.postgresql.org/ for instructions.
The package name for PostgreSQL in the PGDG repository is different. That prevents postgresql packages from being upgraded with a simple yum update. That is by design, because it'd leave you with a surprise major version upgrade - causing at minimum some significant downtime, and probably compatibility problems too.
Read the release notes for each major PostgreSQL release between your 8.4 and the current 9.3, i.e read the notes for 9.0, 9.1, 9.2 and 9.3 (especially the compatibility sections).
Then to install 9.3:
yum install postgresql93-server postgresql93-contrib
This will not upgrade your current server. It will add a new one. You can then migrate the data with pg_upgrade or a dump and reload, change the port so that 9.3 runs on port 5432, and when you're done, stop and uninstall 8.4.
For more info, see the README.rpm-dist at /usr/share/doc/postgresql93/README.rpm-dist after installing postgresql93 packages.
