首先

使用Application Stream (AppStream) 在CentOS 8上安装PostgreSQL 10。
父篇：将来有计划创建
参考：RHEL 8的软件包结构 – BaseOS和Application Stream – 红帽工程师博客

支持

如果使用这种方法，根据《Red Hat Enterprise Linux 8 Application Streams Life Cycle – Red Hat Customer Portal》的说法，预计2024年5月为EOL（存在终止）日期。
之后可能不会对报告的漏洞和问题进行处理。

自動启动设置/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

确认的多种形式

# which postgres
/usr/bin/postgres

# which psql
/usr/bin/psql

# psql --version
psql (PostgreSQL) 10.6
