CREATE USER

CREATE USER — 定义一个新的数据库角色

概要

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，默认假定为 LOGIN，而当命令拼写为 CREATE ROLE 时，默认假定为 NOLOGIN。

兼容性

The CREATE USER statement is a PostgreSQL extension. The SQL standard leaves the definition of users to the implementation.
