Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).
The program yum-complete-transaction is found in the yum-utils package.

三、创建用户和数据目录
#新增postgres用户：
useradd -m postgres
#修改postgres用户密码:passwd postgres（这里设置密码为postgres）
passwd postgres --修改postgres用户密码
mkdir -p /data/pg11data
chmod 700 /data/pg11data
chown postgres:postgres /data/pg11data
四、初始化数据库
数据目录在 /data/pg11data
使用postgresql-11-setup 初始化数据库
vi /usr/lib/systemd/system/postgresql-11.service
把Environment=PGDATA=/var/lib/pgsql/11/data/修改为Environment=PGDATA=/data/pg11data/
/usr/pgsql-11/bin/postgresql-11-setup initdb #初始化
systemctl enable postgresql-11 #设置开机启动
systemctl start postgresql-11 #启动postgresql服务
登录postgresql并设置密码
设置用户 postgres 密码 postgres
su - postgres
psql
ALTER USER postgres WITH PASSWORD 'postgres';
数据库登录权限设置
开启远程访问
vi /data/pg11data/postgresql.conf
修改#listen_addresses = ‘localhost’ 为 listen_addresses=’*’
当然，此处‘*’也可以改为任何你想开放的服务器IP
如有需要修改端口
vi/data/pg11data/postgresql.conf
修改#port =5432 为 port =端口
信任远程连接
vi /data/pg11data/pg_hba.conf
修改如下内容，信任指定服务器连接
# IPv4 local connections:
host all all 127.0.0.1/32 trust
host all all 0.0.0.0/0 password
打开防火墙
CentOS 防火墙中内置了PostgreSQL服务，配置文件位置在/usr/lib/firewalld/services/postgresql.xml，我们只需以服务方式将PostgreSQL服务开放即可。
#开机启用防火墙
systemctl enable firewalld
#开启防火墙
systemctl start firewalld
#开放postgresql服务
firewall-cmd --add-service=postgresql --permanent
#或者可以直接添加端口
firewall-cmd --zone=public --add-port=5432/tcp --permanent
#重载防火墙
firewall-cmd --reload
#查看占用端口
firewall-cmd --list-ports
五、测试使用
因为postgres属于superuser，我们需要创建部分低权限用户
创建数据库
CREATE DATABASE testdb;
创建用户
CREATE USER testuser CREATEDB LOGIN PASSWORD 'testpassword';
将testdb所有权限赋给用户testuser
GRANT ALL ON DATABASE testdb TO testuser;
删除数据库
drop database testdb;
删除用户
drop role testuser;
打开JIT开关
postgres=# set jit=on;
SET
postgres=# select name,setting from pg_settings where name like 'jit%';
name | setting
-------------------------+---------
jit | on
jit_above_cost | 100000
jit_debugging_support | off
jit_dump_bitcode | off
jit_expressions | on
jit_inline_above_cost | 500000
jit_optimize_above_cost | 500000
jit_profiling_support | off
jit_provider | llvmjit
jit_tuple_deforming | on
(10 rows)
创建测试数据：
postgres=# create table ttt (a int, b text, c date );
CREATE TABLE
postgres=# insert into ttt (a,b,c) select aa.*, md5(aa::text), now() from generate_series(1,10000000) aa;
INSERT 0 10000000
JIT对比测试
postgres=# set jit_above_cost=5;
SET
postgres=# set jit_inline_above_cost=5;
SET
postgres=# set jit_optimize_above_cost=5;
SET
postgres=# set jit=off;
SET
postgres=# explain analyze select sum(a) from ttt;
