CREATE USER

创建用户——定义一个新的数据库角色

Synopsis

CREATE USER name [ [ WITH ] option [ ... ] ]

where option can be:

      SUPERUSER | NOSUPERUSER
    | CREATEDB | NOCREATEDB
    | CREATEROLE | NOCREATEROLE
    | INHERIT | NOINHERIT
    | LOGIN | NOLOGIN
    | REPLICATION | NOREPLICATION
    | BYPASSRLS | NOBYPASSRLS
    | CONNECTION LIMIT connlimit
    | [ ENCRYPTED ] PASSWORD 'password' | PASSWORD NULL
    | VALID UNTIL 'timestamp'
    | IN ROLE role_name [, ...]
    | IN GROUP role_name [, ...]
    | ROLE role_name [, ...]
    | ADMIN role_name [, ...]
    | USER role_name [, ...]
    | SYSID uid

Description

CREATE USER 现在是 CREATE ROLE 的别名。唯一不同的是，当命令拼写为 CREATE USER 时，默认为 LOGIN ，而当命令拼写为 CREATE ROLE 时，默认为 NOLOGIN 。

Compatibility

CREATE USER 语句是 PostgreSQL 扩展。SQL 标准把用户定义留给实现。
