postgresql - 无法安装 pgcrypto

Question

我是 postgres 的新手，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，我查看了谷歌上的几个命令并尝试了以下命令:

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

我在centos 上使用postgres 11.3。请让我知道适当的命令/链接，我可以从那里下载/安装 pgcrypto。任何帮助将不胜感激。

谢谢，
