使 libpq 丢弃在 SSL 或 GSS 协议协商期间收到的错误消息（Jacob Champion）§

\n

在加密协商完成之前收到的错误消息可能是由中间人注入的，而不是真正的服务器输出。报告该消息会带来各种安全隐患；例如，该消息可能伪造查询结果，粗心的用户可能会误以为是正确的输出。最好的方案似乎是丢弃这类数据，仅依赖 libpq 自身对连接失败的报告。

修复 SET SESSION AUTHORIZATION 与 SET ROLE 之间意外的交互（Tom Lane）§ §

\n

SQL 标准要求 SET SESSION AUTHORIZATION 具有执行 SET ROLE NONE 的副作用。我们对此的实现有缺陷，导致两个设置之间产生了超出预期的交互。值得注意的是，回滚一个执行了 SET SESSION AUTHORIZATION 的事务会将 ROLE 恢复为 NONE，即使之前并非如此，因此有效用户 ID 现在可能与事务之前不同。在函数 SET 子句中临时设置 session_authorization 也有类似的效果。一个相关的错误是，如果并行工作进程检查 current_setting('role')，它会看到 none，即使它应该看到其他值。

防止在 pg_dump 期间执行未经授权的代码（Masahiko Sawada）§

\n

能够创建和删除非临时对象的攻击者可以注入 SQL 代码，该代码将由并发的 pg_dump 会话以运行 pg_dump 的角色权限（通常是超级用户）来执行。该攻击涉及将序列或类似对象替换为会执行恶意代码的视图或外部表。为防止此问题，引入了新的服务器参数 restrict_nonsystem_relation_kind，可以禁止展开非内置视图以及访问外部表，并教会 pg_dump 在可用时设置该参数。请注意，只有当 pg_dump 和它正在导出的服务器都足够新以包含此修复时，才能防止该攻击。

The attack involves replacing a sequence or similar object with a view or foreign table that will execute malicious code. To prevent this, introduce a new server parameter restrict_nonsystem_relation_kind that can disable expansion of non-builtin views as well as access to foreign tables, and teach pg_dump to set it when available.

修复涉及不一致的基于索引的约束时 ALTER TABLE DETACH PARTITION 的问题（Álvaro Herrera，Tender Wang）§ §

修复递归返回 RECORD 类型的 PL/Python 函数（Tom Lane）§

加强 REFRESH MATERIALIZED VIEW CONCURRENTLY 中的安全限制（Heikki Linnakangas）§ §

\n

并发刷新命令的一个步骤在弱安全限制下运行。如果物化视图的所有者能够说服超级用户或其他高权限用户对该视图执行并发刷新，则视图所有者可以控制以运行 REFRESH 的用户权限执行的代码。修复了这个问题，使所有用户确定的代码都以视图所有者身份运行，这是预期的行为。

此错误的唯一已知利用方式在 PostgreSQL 16.0 及更高版本中不起作用，因此 v16 在实际中可能不受影响。

修复 pg_dump，使得在枚举类型列上进行 hash 分区的分区表可以成功恢复（Tom Lane）§

\n

由于枚举值的 hash 码依赖于分配给枚举的 OID，在导出和恢复后它们通常是不同的，这意味着行往往需要进入与原来不同的分区。用户可以通过指定 --load-via-partition-root 选项来解决此问题；但由于不使用该选项几乎不可能成功，因此让 pg_dump 对此类表自动应用该选项。

同时，修复 pg_restore，使其在使用 --load-via-partition-root 模式时不再尝试在恢复前 TRUNCATE 目标表。这避免了死锁和数据丢失的风险。

将时区数据文件更新为 tzdata 2022f 版本，包含智利、斐济、伊朗、约旦、墨西哥、巴勒斯坦和叙利亚的夏令时法规变更，以及智利、克里米亚、伊朗和墨西哥的历史修正。（Tom Lane）§

此外，Europe/Kiev 时区已重命名为 Europe/Kyiv。另外，以下时区已合并到附近的、人口更多的、自 1970 年以来时钟一致的时区中：Antarctica/Vostok、Asia/Brunei、Asia/Kuala_Lumpur、Atlantic/Reykjavik、Europe/Amsterdam、Europe/Copenhagen、Europe/Luxembourg、Europe/Monaco、Europe/Oslo、Europe/Stockholm、Indian/Christmas、Indian/Cocos、Indian/Kerguelen、Indian/Mahe、Indian/Reunion、Pacific/Chuuk、Pacific/Funafuti、Pacific/Majuro、Pacific/Pohnpei、Pacific/Wake 和 Pacific/Wallis。（这间接影响了已经是这些时区别名的时区：Arctic/Longyearbyen、Atlantic/Jan_Mayen、Iceland、Pacific/Ponape、Pacific/Truk 和 Pacific/Yap。）America/Nipigon、America/Rainy_River、America/Thunder_Bay、Europe/Uzhgorod 和 Europe/Zaporozhye 也被合并到附近的时区中，因为发现它们声称的 1970 年后与这些时区的差异似乎是错误的。在所有这些情况下，之前的时区名称仍作为别名保留；但实际数据是所合并到的时区的数据。

这些时区合并导致被合并时区的 1970 年前时区历史丢失，这对于期望 timestamptz 显示一致性的应用程序可能造成困扰。例如，存储的值 1944-06-01 12:00 UTC 在选择 Europe/Stockholm 时区时，之前会显示为 1944-06-01 13:00:00+01，但现在会显示为 1944-06-01 14:00:00+02。

(Tom Lane) Also, the Europe/Kiev zone has been renamed to Europe/Kyiv. Also, the following zones have been merged into nearby, more-populous zones whose clocks have agreed with them since 1970: Antarctica/Vostok, Asia/Brunei, Asia/Kuala_Lumpur, Atlantic/Reykjavik, Europe/Amsterdam, Europe/Copenhagen, Europe/Luxembourg, Europe/Monaco, Europe/Oslo, Europe/Stockholm, Indian/Christmas, Indian/Cocos, Indian/Kerguelen, Indian/Mahe, Indian/Reunion, Pacific/Chuuk, Pacific/Funafuti, Pacific/Majuro, Pacific/Pohnpei, Pacific/Wake and Pacific/Wallis. (This indirectly affects zones that were already links to one of these: Arctic/Longyearbyen, Atlantic/Jan_Mayen, Iceland, Pacific/Ponape, Pacific/Truk, and Pacific/Yap.) America/Nipigon, America/Rainy_River, America/Thunder_Bay, Europe/Uzhgorod, and Europe/Zaporozhye were also merged into nearby zones after discovering that their claimed post-1970 differences from those zones seem to have been errors. In all these cases, the previous zone name remains as an alias; but the actual data is that of the zone that was merged into. These zone mergers result in loss of pre-1970 timezone history for the merged zones, which may be troublesome for applications expecting consistency of timestamptz display. As an example, the stored value 1944-06-01 12:00 UTC would previously display as 1944-06-01 13:00:00+01 if the Europe/Stockholm zone is selected, but now it will read out as 1944-06-01 14:00:00+02. It is possible to build the time zone data files with options that will restore the older zone data, but that choice also inserts a lot of other old (and typically poorly-attested) zone data, resulting in more total changes from the previous release than accepting these upstream changes does. PostgreSQL has chosen to ship the tzdb data as-recommended, and so far as we are aware most major operating system distributions are doing likewise. However, if these changes cause significant problems for your application, a possible solution is to install a local build of the time zone data files using tzdb's backwards-compatibility options (see their PACKRATDATA and PACKRATLIST options).", "commit_aliases": ["97bb80b1b", "b1cb77bdf", "b3326a753", "c3d16eb3d", "e7c7605a7", "ebf48810b", "ec9a000d8"], "source_commits": ["ec9a000d8"], "source_entry_id": "12.13/changes/038", "db_id": "398737ed13303adc228543ddfa6785a6", "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"], "statement_hash": "b13433443b8b0d38d045f78d09420f3b65ba9de0c3d1bc3d4504ee1593ac743a", "relations": [{"rule": 2, "type": "equivalent", "target": "167682f1e2c3002ccf77abc76fa35274", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"], "statement_hash": "b13433443b8b0d38d045f78d09420f3b65ba9de0c3d1bc3d4504ee1593ac743a"}}, {"rule": 2, "type": "equivalent", "target": "93801251acd5adc5bfb88612d85cd8ba", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"], "statement_hash": "b13433443b8b0d38d045f78d09420f3b65ba9de0c3d1bc3d4504ee1593ac743a"}}, {"rule": 2, "type": "equivalent", "target": "a9cf2408bf63db6ad19bec8fdd8a5d82", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"]}}, {"rule": 2, "type": "equivalent", "target": "d958e11d9207994f5bd3d8b82cf66177", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"]}}, {"rule": 2, "type": "equivalent", "target": "f2dcd5418d27698c2ae57147c96c72ce", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"], "statement_hash": "b13433443b8b0d38d045f78d09420f3b65ba9de0c3d1bc3d4504ee1593ac743a"}}], "version": "12.13", "category_label": "其他改进", "also_in": [], "variants": [], "related_changes": [{"db_id": "93801251acd5adc5bfb88612d85cd8ba", "kind": "equivalent", "version": "15.1", "label": "15.1", "title": "将时区数据文件更新为 tzdata 2022f 版本，包含智利、斐济、伊朗、约旦、墨西哥、巴勒斯坦和叙利亚的夏令时法规变更，以及智利、克里米亚、伊朗和墨西哥的历史修正。", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"], "statement_hash": "b13433443b8b0d38d045f78d09420f3b65ba9de0c3d1bc3d4504ee1593ac743a"}, "url": "/docs/compare/?release=15.1#15.1-c1dde3372032adeb", "source_url": "/docs/release/15.1/#ZH-AUTO-RELEASE-15-SECT2-34"}, {"db_id": "f2dcd5418d27698c2ae57147c96c72ce", "kind": "equivalent", "version": "14.6", "label": "14.6", "title": "将时区数据文件更新为 tzdata 2022f 版本，包含智利、斐济、伊朗、约旦、墨西哥、巴勒斯坦和叙利亚的夏令时法规变更，以及智利、克里米亚、伊朗和墨西哥的历史修正。", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"], "statement_hash": "b13433443b8b0d38d045f78d09420f3b65ba9de0c3d1bc3d4504ee1593ac743a"}, "url": "/docs/compare/?release=14.6#14.6-c9377e72084a56fc", "source_url": "/docs/release/14.6/#ZH-AUTO-RELEASE-14-SECT2-34"}, {"db_id": "167682f1e2c3002ccf77abc76fa35274", "kind": "equivalent", "version": "13.9", "label": "13.9", "title": "将时区数据文件更新为 tzdata 2022f 版本，包含智利、斐济、伊朗、约旦、墨西哥、巴勒斯坦和叙利亚的夏令时法规变更，以及智利、克里米亚、伊朗和墨西哥的历史修正。", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"], "statement_hash": "b13433443b8b0d38d045f78d09420f3b65ba9de0c3d1bc3d4504ee1593ac743a"}, "url": "/docs/compare/?release=13.9#13.9-6c593cfc47cc78d3", "source_url": "/docs/release/13.9/#id-1.11.6.20.5"}, {"db_id": "a9cf2408bf63db6ad19bec8fdd8a5d82", "kind": "equivalent", "version": "11.18", "label": "11.18", "title": "将时区数据文件更新到 tzdata 2022f 版，以反映智利、斐济、伊朗、约旦、墨西哥、巴勒斯坦和叙利亚的夏令时法规变更，并修正智利、克里米亚、伊朗和墨西哥的历史数据。", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"]}, "url": "/docs/compare/?release=11.18#11.18-88c7b21b2ad9d698", "source_url": "/docs/release/11.18/#id-1.11.6.9.5"}, {"db_id": "d958e11d9207994f5bd3d8b82cf66177", "kind": "equivalent", "version": "10.23", "label": "10.23", "title": "将时区数据文件更新到 tzdata 2022f 版，以反映智利、斐济、伊朗、约旦、墨西哥、巴勒斯坦和叙利亚的夏令时法规变更，并修正智利、克里米亚、伊朗和墨西哥的历史数据。", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"]}, "url": "/docs/compare/?release=10.23#10.23-88c7b21b2ad9d698", "source_url": "/docs/release/10.23/#id-1.11.6.5.6"}]}]}, {"date": "2022-08-11", "build": "12.12", "major": "12", "minor": 12, "manual": "12", "status": "stable", "doc_git": "", "version": "12.12", "eol_date": "2024-11-21", "date_text": "2022-08-11", "supported": false, "manual_url": "/docs/12/release-12-12.html", "source_url": "/docs/release/12.12/", "entry_count": 39, "placeholder": false, "content_hash": "c8dfe5a86b6a2715be6c29ca57e850806b59dea46ba025c54cf041db00f751d7", "manual_build": "12.22", "source_as_of": "", "changes_count": 39, "doc_loaded_at": "2026-09-26T02:56:41.471523", "migration_html": "

As a side benefit, it also reduces the risk of accidentally replacing objects one did not mean to. The PostgreSQL Project thanks Sven Klemm for reporting this problem.

修复检查事务可见性时的竞态条件（Simon Riggs）§

安排在 SPI_commit() 中的提交时错误后进行清理，而不是期望调用者来做（Peter Eisentraut，Tom Lane）§ §

正确的清理很复杂，需要使用底层设施，因此已知的调用者没有一个做对了也不足为奇。这导致当 PL 过程执行 COMMIT 但发生失败（如延迟约束检查）时出现异常行为。为了改善情况，将 SPI_commit() 重新定义为启动一个新事务，使其等价于 SPI_commit_and_chain()，只是获得默认事务特性而不是保留先前事务的特性。为了使此更改在 API 层面具有一定透明性，将 SPI_start_transaction() 重新定义为空操作。所有已知的 SPI_commit() 调用者都会立即调用 SPI_start_transaction()，因此它们不会注意到任何变化。类似的说明适用于 SPI_rollback()。

\n

另外修复了 PL/Python，它完全遗漏了对此类错误的任何处理，导致跳出 Python 解释器。据报告这会导致 Python 3.11 崩溃。较旧的 Python 版本会泄漏一些内存，但似乎在其他方面没有问题。

This led to misbehaviors when a PL procedure issued COMMIT but a failure occurred (such as a deferred constraint check). To improve matters, redefine SPI_commit() as starting a new transaction, so that it becomes equivalent to SPI_commit_and_chain() except that you get default transaction characteristics instead of preserving the prior transaction's characteristics. To make this somewhat transparent API-wise, redefine SPI_start_transaction() as a no-op.

停止将查询提供的列别名用于引用普通表的整行变量的列（Tom Lane）§

\n

整行变量（例如在 SELECT 列表顶层以外的上下文中的 tbl.*）产生的元组中的列名，现在始终为关联的命名复合类型的列名（如果有的话）。之前我们曾尝试使其跟踪已应用于该变量所引用的 FROM 条目的任何列别名。但这在语义上是有问题的，因为这样变量的输出实际上根本不是它声称的复合类型。之前处理这种不一致性的尝试产生了糟糕的结果，甚至包括在磁盘上存储不可读的数据，因此放弃了整个想法。

\n

在需要重新标记这些列的情况下，一种变通方法是引入一个额外的子 SELECT 层级，使整行变量引用子 SELECT 的输出而非普通表。这样变量一开始就是 record 类型，就不存在这个问题了。

This is problematic since standby servers may already have copies of that WAL segment. They will then see an inconsistent next segment, and will not be able to recover without manual intervention.

Instead write a new type of WAL record at the start of the next WAL segment, informing readers that the incomplete WAL record will never be finished and must be disregarded.

在 Windows 上运行时，initdb 尝试将新集簇的 timezone 参数设置为与系统当前时区匹配的 IANA 时区。我们使用的是多年前生成的映射表，并且只是零星地更新；不出所料，它包含许多错误以及遗漏了最近添加的时区。事实证明 CLDR 一直在跟踪最合适的映射，所以开始使用他们的数据。此更改不会影响任何现有安装，仅影响新初始化的集簇。

Also force NO SCROLL mode for the implicit cursor used by a PL/pgSQL FOR-over-query loop, to avoid this type of problem when persisting such a cursor during an intra-procedure commit.", "commit_aliases": ["182323300", "2757865fa", "5b7bf9f72", "ba2c6d6ce", "be9009890", "c1fd756fd", "c3b508268", "c5b281841"], "source_commits": ["182323300", "c3b508268"], "source_entry_id": "12.8/changes/004", "db_id": "8762a1f0f0742f39d0293631f3055182", "patch_ids": ["52218db81227e885ec8726bea84ddb4d", "94138ee8c5874b4518161b6c7421ad5c"], "statement_hash": "66c1bc5c866bc946463bad580c6e29f1c32b9b1444e4cdfdcf00e74de2d0c96b", "relations": [{"rule": 2, "type": "equivalent", "target": "1011c295745d3430366bead25ca6433c", "evidence": {"same_day": true, "patch_ids": ["52218db81227e885ec8726bea84ddb4d", "94138ee8c5874b4518161b6c7421ad5c"], "statement_hash": "66c1bc5c866bc946463bad580c6e29f1c32b9b1444e4cdfdcf00e74de2d0c96b"}}, {"rule": 2, "type": "equivalent", "target": "ebcf2aff50e3122c29ee032f52a6fa86", "evidence": {"same_day": true, "patch_ids": ["52218db81227e885ec8726bea84ddb4d", "94138ee8c5874b4518161b6c7421ad5c"], "statement_hash": "66c1bc5c866bc946463bad580c6e29f1c32b9b1444e4cdfdcf00e74de2d0c96b"}}], "version": "12.8", "category_label": "其他改进", "also_in": [], "variants": [], "related_changes": [{"db_id": "1011c295745d3430366bead25ca6433c", "kind": "equivalent", "version": "13.4", "label": "13.4", "title": "避免持久化读取非稳定查询的游标输出时出现异常行为", "evidence": {"same_day": true, "patch_ids": ["52218db81227e885ec8726bea84ddb4d", "94138ee8c5874b4518161b6c7421ad5c"], "statement_hash": "66c1bc5c866bc946463bad580c6e29f1c32b9b1444e4cdfdcf00e74de2d0c96b"}, "url": "/docs/compare/?release=13.4#13.4-c567b2519748e23e", "source_url": "/docs/release/13.4/#id-1.11.6.25.5"}, {"db_id": "ebcf2aff50e3122c29ee032f52a6fa86", "kind": "equivalent", "version": "11.13", "label": "11.13", "title": "避免持久化读取非稳定查询的游标输出时出现异常行为", "evidence": {"same_day": true, "patch_ids": ["52218db81227e885ec8726bea84ddb4d", "94138ee8c5874b4518161b6c7421ad5c"], "statement_hash": "66c1bc5c866bc946463bad580c6e29f1c32b9b1444e4cdfdcf00e74de2d0c96b"}, "url": "/docs/compare/?release=11.13#11.13-acab17afcf133c09", "source_url": "/docs/release/11.13/#id-1.11.6.14.5"}]}, {"id": "12.8-8f803134c4475494", "cves": [], "html": "

修复 TRUNCATE ... CASCADE，确保截断所有相关分区（Jehan-Guillaume de Rorthais）§

如果使用 CASCADE 选项截断分区表的一个分区，且另一个表通过外键引用该分区表，则另一个表也必须被截断。当引用表本身也是分区表时，遗漏了这一检查，可能使违反外键约束的行保留下来。
