2.2安装新版本postgresql

[root@localhost postgresql]# tar -xvf postgresql-14.11.tar.bz2

[root@localhost postgresql]# cd postgresql-14.11

#创建安装目录
[root@localhost postgresql-14.11]# mkdir -p  /usr/local/pgsql14.11

#编译安装
[root@localhost postgresql-14.11]# ./configure --prefix=/usr/local/pgsql14.11 --with-perl --with-python --with-libxml --with-libxslt --with-openssl

[root@localhost postgresql-14.11]# make && make install

#查看是否安装到指定目录：/usr/local/pgsql14.11
[root@localhost pgsql14.11]# pwd
/usr/local/pgsql14.11
[root@localhost pgsql14.11]# ll
total 16
drwxr-xr-x 2 root root 4096 May  2 04:33 bin
drwxr-xr-x 6 root root 4096 May  2 04:33 include
drwxr-xr-x 4 root root 4096 May  2 04:33 lib

[root@localhost pgsql14.11]#

#编译插件
[root@localhost contrib]# pwd
/soft/postgresql/postgresql-14.11/contrib

[root@localhost contrib]# make && make install

 3.生成软连接/替换旧版本安装目录

[root@localhost local]# cd /usr/local
[root@localhost local]# pwd
/usr/local
[root@localhost local]# ll

4.重启pg数据库服务

重启前：

[root@localhost local]# psql postgres postgres
psql (14.11, server 14.6)
Type "help" for help.

postgres=# select version();
                                                 version

postgres=#

重启后：

[root@localhost local]# su - postgres
