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 。

CREATE USER is now an alias for CREATE ROLE. The only difference is that when the command is spelled CREATE USER, LOGIN is assumed by default, whereas NOLOGIN is assumed when the command is spelled CREATE ROLE.

Compatibility

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

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