Postgresql无法识别,即使已经安装

Postgresql 8.4似乎正确安装,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,当我试图运行这个,它是无法识别的:

 $ sudo /sbin/service postgresql initdb postgresql: unrecognized service 

这是RHEL 6.3

您需要安装postgresql-server以获取System V init脚本和服务器二进制文件。
