本文主要实践在麒麟V10版本上通过源码编译安装PostgreSQL12.5，因为是源码编译，所以对于其他版本也具有参考性。
V10
$ uname -a
Linux kylin-v10-02 4.19.90-24.4.v2101.ky10.aarch64 #1 SMP Mon May 24 14:45:37 CST 2021 aarch64 aarch64 aarch64 GNU/Linux
下载地址为官网：https://www.postgresql.org/ftp/source/v12.5/
上传解压到服务器。

运行
./configure
得到如下报错：
error: readline library not found
需要安装readline
yum install readline-devel -y
然后再运行 ./configure
没有报错后，再运行
make
编译完成后得到成功提示
然后开始安装, 运行
make install
安装成功后可以看到
默认安装路径为 /usr/local/pgsql，我们需要将权限改为postgres
[root@kylin-v10-02 local]# useradd postgres
[root@kylin-v10-02 local]# chown -R postgres:postgres /usr/local/pgsql/
安装完成后，还要做一些配置操作.
vim /etc/profile加入下面的环境变量配置
export PATH=/usr/local/pgsql/bin:$PATH
LD_LIBRARY_PATH=/usr/local/pgsql/lib
export LD_LIBRARY_PATH
然后刷新配置：
source /etc/profile
在启动PG之前，需要准备一个数据目录，注意修改权限：
mkdir -p /export/pgdata
chown -R postgres:postgres /export/pgdata
初始化数据库，注意，要切换到postgres用户
# sudo su - postgres
initdb -D /export/pgdata/
完整输出如下：
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale "zh_CN.UTF-8".
The default database encoding has accordingly been set to "UTF8".
initdb: could not find suitable text search configuration for locale "zh_CN.UTF-8"
The default text search configuration will be set to "simple".
Data page checksums are disabled.

initdb: warning: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
Success. You can now start the database server using:
pg_ctl -D /export/pgdata/ -l logfile start
启动PG
那我们就启动服务：
[postgres@kylin-v10-02 ~]$ pg_ctl -D /export/pgdata/ -l logfile start
waiting for server to start.... done
server started
[postgres@kylin-v10-02 ~]$ psql
psql (12.5)
Type "help" for help.

template0 | postgres | UTF8 | zh_CN.UTF-8 | zh_CN.UTF-8 | =c/postgres +
| | | | | postgres=CTc/postgres
template1 | postgres | UTF8 | zh_CN.UTF-8 | zh_CN.UTF-8 | =c/postgres +

(3 rows)
测试ok，不过要提供给其他机器用，还需要一些监听和安全配置。
postgres=# alter user postgres password 'postgres';
ALTER ROLE
默认情况是在localhost上监听 vim /export/pgdata/postgresql.conf ，修改监听地址
listen_addresses = '*'
还要允许密码访问，vim /export/pgdata/pg_hba.conf，在最后加入：
host all all 0.0.0.0/0 md5
然后重启服务
pg_ctl -D /export/pgdata/ -l logfile restart
