允许在部分 hash 索引上进行索引扫描，即使索引的谓词蕴含 WHERE 子句的真值（Tom Lane）§

\n

通常我们会删除被谓词蕴含的 WHERE 子句，因为测试它没有意义——对于每个索引条目，该条件必然成立。然而，如果索引是需要在前导索引键上有 WHERE 子句的类型（如 hash 索引），这样做可能阻止创建索引扫描计划。在考虑此类索引时，不要删除被蕴含的子句。

将 NOTIFY 消息处理期间发生的错误升级为 FATAL，即关闭连接（Heikki Linnakangas）§

\n

以前，如果后端在吸收 NOTIFY 消息时遇到错误，它会跳过该消息，向客户端报告错误，然后继续运行。但这种行为存在很多问题。一个主要问题是，客户端没有好的方法来知道通知丢失了，更无法知道通知的内容是什么。根据应用逻辑的不同，错过一条通知可能导致应用程序卡在等待状态。此外，剩余的消息在有人发送新的 NOTIFY 之前不会被处理。

\n

另外，如果连接在接收到 NOTIFY 信号时处于空闲状态，由于无关的原因，任何 ERROR 都会被升级为 FATAL。因此，我们选择在所有情况下都这样做，以保持一致性，并向应用程序提供一个明确的信号，表明它可能错过了一些通知。

增加新的服务器参数file_extend_method来控制 posix_fallocate() 的使用（Thomas Munro）§

\n

PostgreSQL 版本 16 及更高版本会使用 posix_fallocate()（如果平台提供的话）来扩展关系文件。然而，据报告这与某些文件系统交互不良：BTRFS 压缩会因使用 posix_fallocate() 而被禁用，而在较旧的 Linux 内核版本中 XFS 可能会产生虚假的 ENOSPC 错误。为提供一种解决方案，引入了这个新的服务器参数。将 file_extend_method 设置为 write_zeros 将使服务器回退到通过写入全零数据块来扩展文件的旧方法。
