Postgresql 8.4似乎安装正确,根据这个：
sudo yum install postgresql Loaded plugins: product-id,refresh-packagekit,rhnplugin,security,subscription-manager This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. This system is receiving updates from RHN Classic or RHN Satellite. Setting up Install Process Package postgresql-8.4.13-1.el6_3.x86_64 already installed and latest version Nothing to do
但是,当我尝试运行它时,它无法识别：
$sudo /sbin/service postgresql initdb postgresql: unrecognized service
这是RHEL 6.3
