首先

使用Application Stream（AppStream）在CentOS8上安装PostgreSQL 10。
原文：暂未创建
参考：RHEL8的软件包结构 – BaseOS和Application Stream – 赤帽工程师博客

支持

如果使用这种方法进行引入，根据红帽企业 Linux 8 应用流生命周期 – 红帽客户门户网站，2021年11月被认为是终止支持 (EOL) 的。
此后，对于报告的漏洞和问题可能不会进行处理。

自动启动/取消设置PostgreSQL

# systemctl enable postgresql
Created symlink /etc/systemd/system/multi-user.target.wants/postgresql.service → /usr/lib/systemd/system/postgresql.service.

# systemctl list-unit-files --type=service |grep postgresql
postgresql.service                          enabled
postgresql@.service                         disabled

# systemctl disable postgresql
Removed /etc/systemd/system/multi-user.target.wants/postgresql.service.

# systemctl list-unit-files --type=service |grep postgresql
postgresql.service                          disabled
postgresql@.service                         disabled

确认的各种方式

# which postgres
/usr/bin/postgres

# which psql
/usr/bin/psql

# psql --version
psql (PostgreSQL) 9.6.10
