记录一次postgresql升级和pg_pathman的安装

初始环境

centos7 postgresql9.4

psql升级

根据官网：https://www.postgresql.org/download/linux/redhat/

1. Install the repository RPM:

yum install https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm

2. Install the client packages

yum install postgresql96

3. Optionally install the server packages:

yum install postgresql96-server

pg_pathman安装

1. 获取源代码

git clone https://github.com/postgrespro/pg_pathman

2. root下编译

make USE_PGXS=1
make USE_PGXS

如果报错pg_config不存在，则安装pg_cofig

yum install postgresql96-devel

3. make成功后修改postgresql.conf

打开postgresql.conf：将shared_preload_libraries配置改为如下
shared_preload_libraries = 'pg_pathman'

4. 重启psql

附：

1. 增加用户

create user xxx

2. 修改用户密码

alter user xxx with password 'xxx';

3. 执行分表

CREATE EXTENSION pg_pathman；
SELECT create_hash_partitions('bbs_reply', 'thread_id', 128); ＃bbs_reply表名，thread_id字段名，128分表数量
