[root@centos63 ~]# wget http://yum.pgrpms.org/9.2/redhat/rhel-6-i386/pgdg-centos92-9.2-5.noarch.rpm --2012-09-25 21:50:05-- http://yum.pgrpms.org/9.2/redhat/rhel-6-i386/pgdg-centos92-9.2-5.noarch.rpm Resolving yum.pgrpms.org... 98.129.198.114 Connecting to yum.pgrpms.org|98.129.198.114|:80... connected.

2. Install the repo :
[root@centos63 ~]# rpm -ivh pgdg-centos92-9.2-5.noarch.rpm Preparing... ########################################### [100%] 1:pgdg-centos92 ########################################### [100%]
3. Edit the CentOS-Base.repo to exclude postgreql.
[root@centos63 ~]# vi /etc/yum.repos.d/CentOS-Base.repo
Add ‘exclude=postgresql*’ to the [base] and [updates] sections:
[base] name=CentOS-$releasever - Base mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 exclude=postgresql* #released updates [updates] name=CentOS-$releasever - Updates mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates #baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 exclude=postgresql*
4. Use ‘yum list’ to check the packages that are now available.
[root@centos63 ~]# yum list postgres* Loaded plugins: fastestmirror, presto, priorities Loading mirror speeds from cached hostfile * base: centos.ipserverone.com * extras: centos.ipserverone.com * updates: centos.ipserverone.com Available Packages postgresql.i686 8.4.11-1.el6_2 CentOS6.3-Repository postgresql-contrib.i686 8.4.11-1.el6_2 CentOS6.3-Repository postgresql-devel.i686 8.4.11-1.el6_2 CentOS6.3-Repository postgresql-docs.i686 8.4.11-1.el6_2 CentOS6.3-Repository postgresql-jdbc.i686 8.4.701-3.el6 CentOS6.3-Repository postgresql-jdbc.noarch 8.4.701-8.el6 CentOS6.3-Repository postgresql-libs.i686 8.4.11-1.el6_2 CentOS6.3-Repository postgresql-odbc.i686 08.04.0200-1.el6 CentOS6.3-Repository postgresql-plperl.i686 8.4.11-1.el6_2 CentOS6.3-Repository postgresql-plpython.i686 8.4.11-1.el6_2 CentOS6.3-Repository postgresql-pltcl.i686 8.4.11-1.el6_2 CentOS6.3-Repository postgresql-server.i686 8.4.11-1.el6_2 CentOS6.3-Repository postgresql-test.i686 8.4.11-1.el6_2 CentOS6.3-Repository postgresql92.i686 9.2.1-1PGDG.rhel6 pgdg92 postgresql92-contrib.i686 9.2.1-1PGDG.rhel6 pgdg92 postgresql92-debuginfo.i686 9.2.1-1PGDG.rhel6 pgdg92 postgresql92-devel.i686 9.2.1-1PGDG.rhel6 pgdg92 postgresql92-docs.i686 9.2.1-1PGDG.rhel6 pgdg92 postgresql92-libs.i686 9.2.1-1PGDG.rhel6 pgdg92 postgresql92-odbc.i686 09.01.0200-1PGDG.rhel6 pgdg92 postgresql92-odbc-debuginfo.i686 09.01.0200-1PGDG.rhel6 pgdg92 postgresql92-plperl.i686 9.2.1-1PGDG.rhel6 pgdg92 postgresql92-plpython.i686 9.2.1-1PGDG.rhel6 pgdg92 postgresql92-pltcl.i686 9.2.1-1PGDG.rhel6 pgdg92 postgresql92-server.i686 9.2.1-1PGDG.rhel6 pgdg92 postgresql92-tcl.i686 2.0.0-1.rhel6 pgdg92 postgresql92-tcl-debuginfo.i686 2.0.0-1.rhel6 pgdg92 postgresql92-test.i686 9.2.1-1PGDG.rhel6 pgdg92
5. Start install PostgreSQL 9 using yum:
[root@centos63 ~]# yum install postgresql92 postgresql92-devel postgresql92-server postgresql92-libs postgresql92-contrib -y
6. Verify, Initialize and Start PostgreSQL service :
[root@centos63 ~]# service postgresql-9.2 status is stopped [root@centos63 ~]# service postgresql-9.2 initdb Initializing database: [ OK ] [root@centos63 ~]# service postgresql-9.2 start Starting postgresql-9.2 service: [ OK ]
