无法安装pgcrypto

Question

我是postgres新手，我需要下载并安装pgcrypto扩展。我在命令下运行，但什么也没有发生：

    [root@localhost /]# yum install pgcrypto
   Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirror.nbrc.ac.in
* extras: mirrors.nhanhoa.com
 * updates: mirror.nbrc.ac.in
No package pgcrypto available.
Error: Nothing to do

然后，我查看了google上的几个命令，并尝试使用以下命令：

    [root@localhost ~]# gppkg -r pgcrypto
-bash: gppkg: command not found

我在centos上使用postgres 11.3。请让我知道合适的命令/链接，我可以从那里下载/安装pgcrypto。任何帮助都将不胜感激。

谢谢
