Chris van Eijk:ALTER DEFAULT PRIVILEGES 不生效?我们的实测结果

PostgreSQL 的 ALTER DEFAULT PRIVILEGES 仅对指定创建角色之后新建的对象生效,且只在创建时读取一次。常见失效原因包括:未用 FOR ROLE 指定实际建表角色,或对象由其他角色创建、事后更改属主或移动 schema。按 schema 撤销无法覆盖全局默认权限,需先全局撤销再按 schema 授予。序列和函数需单独设置,默认权限不涉及行级安全。

Default Actor Isolation:好初衷带来的新问题

Swift 6.2 引入的 Default Actor Isolation 功能旨在简化并发编程,减轻开发者在单线程场景下的负担。它自动推断代码运行在 MainActor 上,减少了 Sendable 和 @MainActor 声明的使用,但仍需注意使用 nonisolated 关键字以避免编译错误。该功能促进了模块化编程,但在某些情况下与显式 @MainActor 存在差异。
