采用RLS后,不同的用户访问一个表可以看到不同的数据。通过对表增加RSP(行级安全策略,Row Security Policy),控制用户进行查询更新操作。 1.介绍: 默认的话,表没有任何安全策略限制,要想使表有行级安全性,需要使用命令:ALTER TABLE ... ENABLE ROW LEVEL SECURITY; 所有对该表的操作(表的属主除外),都要经过行...
要为表启用 RLS,可以从以下步骤开始: ALTERTABLE[table_name]ENABLEROWLEVELSECURITY 然后添加策略。比方说,您想限制只有已定义在jedi用户组中的可信人员才能读取lightsaber_internals表,这样只有lightsaber的所有者才能查看其内部细节。您可以这样做 ALTERTABLElightsaber_internalsENABLEROWLEVELSECURITY CREATEPOLICYjedi_onlyO...

PostgreSQL是一种开源的关系型数据库管理系统,它支持高级特性和扩展性,如行级安全(Row-Level Security,RLS)。RLS允许数据库管理员定义访问控制策略,以限制用户对数据库中特定行的访问。 要为一个用户应用RLS,可以按照以下步骤进行操作: 创建一个用于定义访问策略的函数:首先,创建一个函数,该函数将确定用户是否有权访...
