O.2. Default Roles Renamed to Predefined Roles #

PostgreSQL 13 及以下版本中使用了“默认角色”。但是，由于这些角色实际上无法更改，并且在初始化时作为系统的一部分进行安装，因此更合适的术语是“预定义角色”。有关预定义角色的当前文档，请参阅 Section 22.5，有关此更改的详细信息，请参阅 the release notes for PostgreSQL 14。

PostgreSQL 13 and below used the term “Default Roles”. However, as these roles are not able to actually be changed and are installed as part of the system at initialization time, the more appropriate term to use is “Predefined Roles”. See Section 22.5 for current documentation regarding Predefined Roles, and the release notes for PostgreSQL 14 for details on this change.
