我的linux版本是centos 6.4 ,准备安装postgresql 9.2
根据官方说明：
http://www.postgresql.org/download/linux/redhat/
缺省只能是8.4版本，如果要安装9.2，必须做一下改动：
rpm -i http://yum.postgresql.org/9.2/redhat/rhel-6-x86_64/pgdg-redhat92-9.2-7.noarch.rpm
yum install postgresql92-server postgresql92-contrib
service postgresql-9.2 initdb
chkconfig postgresql-9.2 on
第一步：
[root@wcf ~]# rpm -i http://yum.postgresql.org/9.2/redhat/rhel-6-x86_64/pgdg-redhat92-9.2-7.noarch.rpm
warning: /var/tmp/rpm-tmp.sTOQTP: Header V4 DSA/SHA1 Signature, key ID 442df0f8: NOKEY
第二步：
root@wcf ~]# yum install postgresql92-server postgresql92-contrib
