記錄一次postgresql升級和pg_pathman的安裝

初始環境

centos7 postgresql9.4

psql升級

根據官網：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安裝

1. 獲取源代碼

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

2. root下編譯

make USE_PGXS=1
make USE_PGXS

若是報錯pg_config不存在，則安裝pg_cofig

yum install postgresql96-devel

3. make成功後修改postgresql.conf

打開postgresql.conf：將shared_preload_libraries配置改成以下
shared_preload_libraries = 'pg_pathman'

4. 重啓psql

附：

1. 增長用戶

create user xxx

2. 修改用戶密碼

alter user xxx with password 'xxx';

3. 執行分表

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