安装过程中如果缺少 MSVCR120.dll、MSVCP120.dll 在网上下载后，将dll文件复制到“ X:\Windows\system32 ” (X代表您系统所在目录盘符，如：C:\Windows\system32 ) 目录下。

2. 相关命令

initdb -D D:\dev\pgsql\data --locale=C

createdb -h 127.0.0.1 test_db

createuser -h 127.0.0.1 test_user

pg_ctl -D D:\dev\pgsql\data start

3. 相关sql

select now();

select * from user_info order by id desc limit 1;

insert into user_info(id,token,valid_time) values(nextval('seq_user_info'),'123',now()- interval '11 days');

delete from user where create_time<(now()+interval('2 months'));

update user_token set status='0' where create_time<(now()-interval('10 days'));

create sequence seq_user minvalue 1 maxvalue 9999999 increment by 1 start with 1 cache 10;

alter table user_info alter column id set default nextval('seq_user_info');

create table user_info(
id integer primary key default nextval('seq_user_info'),
name varchar(40) not null check (name <> '')
);

insert into user_info(name) values ('hfhwfw');
