CREATE USER ​

CREATE USER — 定义一个新的数据库角色

语法 ​

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

描述 ​

CREATE USER现在是CREATE ROLE的别名。唯一的区别是，当命令拼写为CREATE USER时，默认情况下假定LOGIN，而当命令拼写为CREATE ROLE时，默认情况下假定NOLOGIN。

兼容性 ​

CREATE USER语句是PostgreSQL扩展。SQL 标准将用户的定义留给实现。
