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。

\n

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。

避免在复制工作进程中函数语法错误后崩溃（Maxim Orlov，Anton Melnikov，Masahiko Sawada，Tom Lane）

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。

\n

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。

\n

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。

可以使用选项构建时区数据文件来恢复旧的时区数据，但该选择也会插入大量其他旧的（且通常缺乏充分证据的）时区数据，导致相比接受这些上游更改，总变化更多。PostgreSQL 选择按照推荐方式发布 tzdb 数据，据我们所知，大多数主要操作系统发行版也在这样做。但是，如果这些更改给你的应用程序造成了严重问题，一个可能的解决方案是使用 tzdb 的向后兼容选项安装本地构建的时区数据文件（参见其 PACKRATDATA 和 PACKRATLIST 选项）。

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.

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": ["b1cb77bdf"], "source_entry_id": "11.18/changes/032", "db_id": "a9cf2408bf63db6ad19bec8fdd8a5d82", "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"], "statement_hash": "30d272084505d30ea5a6f4e6dfc202d080896dee63d51865c0f4930b84de71b9", "relations": [{"rule": 2, "type": "equivalent", "target": "167682f1e2c3002ccf77abc76fa35274", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"]}}, {"rule": 2, "type": "equivalent", "target": "398737ed13303adc228543ddfa6785a6", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"]}}, {"rule": 2, "type": "equivalent", "target": "93801251acd5adc5bfb88612d85cd8ba", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"]}}, {"rule": 2, "type": "equivalent", "target": "d958e11d9207994f5bd3d8b82cf66177", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"], "statement_hash": "30d272084505d30ea5a6f4e6dfc202d080896dee63d51865c0f4930b84de71b9"}}, {"rule": 2, "type": "equivalent", "target": "f2dcd5418d27698c2ae57147c96c72ce", "evidence": {"same_day": true, "patch_ids": ["601b075d0f82f4e4b897afd21d9ebb1a"]}}], "version": "11.18", "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"]}, "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"]}, "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"]}, "url": "/docs/compare/?release=13.9#13.9-6c593cfc47cc78d3", "source_url": "/docs/release/13.9/#id-1.11.6.20.5"}, {"db_id": "398737ed13303adc228543ddfa6785a6", "kind": "equivalent", "version": "12.13", "label": "12.13", "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"]}, "url": "/docs/compare/?release=12.13#12.13-fe45c73f9a6700aa", "source_url": "/docs/release/12.13/#id-1.11.6.15.5"}, {"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"], "statement_hash": "30d272084505d30ea5a6f4e6dfc202d080896dee63d51865c0f4930b84de71b9"}, "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": "11.17", "major": "11", "minor": 17, "manual": "11", "status": "stable", "doc_git": "", "version": "11.17", "eol_date": "2023-11-09", "date_text": "2022-08-11", "supported": false, "manual_url": "/docs/11/release-11-17.html", "source_url": "/docs/release/11.17/", "entry_count": 37, "placeholder": false, "content_hash": "feacbb440af5d269ac9e1be9f18bd64c7b237946d9fd9bfa4ff72d67884d3a09", "manual_build": "11.22", "source_as_of": "", "changes_count": 37, "doc_loaded_at": "2026-09-26T02:56:42.383207", "migration_html": "

不允许扩展脚本替换不属于该扩展的已有对象（Tom Lane）

支持“原位”表空间（Thomas Munro，Michael Paquier，Álvaro Herrera）

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.

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。

We'd previously attempted to make them track any column aliases that had been applied to the FROM entry the variable refers to.

使 libpq 在 SSL 或 GSS 加密握手后拒绝多余的数据（Tom Lane）

\n

能够向 TCP 连接注入数据的中间人攻击者可以在本应受加密保护的数据库会话开始时塞入一些明文数据。这可能被用来向客户端注入伪造的响应，不过 libpq 行为的其他细节使得这比听起来更难实现。另一种攻击方式是窃取客户端的密码或其他可能在会话早期发送的敏感数据。已证明在受 CVE-2021-23214 漏洞影响的服务器上这是可能的。

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. To fix, do not back up over a WAL segment boundary when restarting after a crash. 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.

修复 float4 和 float8 的 hash 函数，使其对 NaN 产生一致的结果（Tom Lane）

由于 PostgreSQL 的浮点类型将所有 NaN 视为相等，hash 函数必须为所有按 IEEE 754 标准表示 NaN 的位模式生成相同的 hash 值。以前没有做到这一点，因此对于非规范的 NaN 值，hash 索引和基于 hash 的查询计划可能产生错误结果。（在大多数机器上，'-NaN'::float8 就是产生此类值的一种方法。）如果浮点列的 hash 索引有任何可能包含此类值，建议重建这些索引。

防止数组下标计算中的整数溢出（Tom Lane）

提高 contrib 模块安装脚本的安全性（Tom Lane）

修复 ALTER TABLE 中重新验证约束的时机（David Rowley）

避免在使用 PAM 认证时记录有关已放弃连接的报错消息（Tom Lane）

修复 bitshiftright() 的错误行为（Tom Lane）

\n

当位串长度不是 8 的倍数时，位串右移操作符未能将结果最后一个字节中的填充空间清零。虽然大多数操作看不到这些填充位，但其中任何非零位都会导致意外的比较行为，因为位串比较预期这些额外的位始终为零，并未特意忽略它们。

如果由于将 bitshiftright() 的输出保存在表中而导致数据不一致，可以使用类似以下语句进行修复：

在 psql 中，意外丢失连接并成功重新连接后，重新同步关于服务器的内部状态（Peter Billen，Tom Lane）

That will provide about the same performance as before, and it will find all non-empty subsets of the given constant array, which is all that could reliably be expected of the query before.", "commit_aliases": ["113b3d903", "2f76f4182", "5b3e6c13f", "614119d00", "ced272d2d", "e519eded6", "efc77cf5f"], "source_commits": ["113b3d903"], "source_entry_id": "11.6/changes/061", "db_id": "3aca8549b51328708bd5a5bf23277edc", "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e", "relations": [{"rule": 2, "type": "equivalent", "target": "095d1b932d2c8b19ac2c80541fa441c9", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}, {"rule": 2, "type": "equivalent", "target": "1c9f43f55f1b5b56c782ba572b576692", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}, {"rule": 2, "type": "equivalent", "target": "73e885c18b9f26670dcde44f3cce58b1", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}, {"rule": 2, "type": "equivalent", "target": "85ba616e74f33ab854bbdba4c2efb25a", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}], "version": "11.6", "category_label": "BUG 修复", "also_in": [], "variants": [], "related_changes": [{"db_id": "095d1b932d2c8b19ac2c80541fa441c9", "kind": "equivalent", "version": "10.11", "label": "10.11", "title": "修复 contrib/intarray 的 GiST 操作符类，使其在空数组上使用 <@ 时不会失败", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=10.11#10.11-5ed18192f91e54e7", "source_url": "/docs/release/10.11/#id-1.11.6.17.5"}, {"db_id": "73e885c18b9f26670dcde44f3cce58b1", "kind": "equivalent", "version": "9.6.16", "label": "9.6.16", "title": "修复 contrib/intarray 的 GiST 操作符类在空数组使用 <@ 时不失败的问题", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=9.6.16#9.6.16-059f1bbda100d67f", "source_url": "/docs/release/9.6.16/#id-1.11.6.13.5"}, {"db_id": "1c9f43f55f1b5b56c782ba572b576692", "kind": "equivalent", "version": "9.5.20", "label": "9.5.20", "title": "修复 contrib/intarray 的 GiST 操作符类在空数组使用 <@ 时不失败的问题", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=9.5.20#9.5.20-059f1bbda100d67f", "source_url": "/docs/release/9.5.20/#id-1.11.6.10.5"}, {"db_id": "85ba616e74f33ab854bbdba4c2efb25a", "kind": "equivalent", "version": "9.4.25", "label": "9.4.25", "title": "修复 contrib/intarray 的 GiST 操作符类在空数组使用 <@ 时不失败的问题", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=9.4.25#9.4.25-059f1bbda100d67f", "source_url": "/docs/release/9.4.25/#id-1.11.6.6.6"}]}, {"id": "11.6-dceb1e7c16b596f4", "cves": [], "html": "

建立依赖关系以防止删除分区键列（Tom Lane）

\n

ALTER TABLE ... DROP COLUMN 会拒绝删除分区键列。但间接删除（例如删除键列的数据类型所引发的级联删除）没有这样的检查，因此可能删除键列。这会使分区表严重损坏，既无法访问也无法删除。

\n

改进 initdb 对系统时区多个等效名称的处理（Tom Lane，Andrew Gierth）

\n

如果 /etc/localtime 符号链接存在，则让 initdb 检查它，以便在系统时区的多个等效名称之间作出选择。这使 initdb 在存在多个相同时区时，更有可能选择用户预期的时区名。如果 /etc/localtime 不是指向时区数据文件的符号链接，或者时区是由 TZ 环境变量确定的，则行为不变。

\n

另外，如果 TZ 和 /etc/localtime 都未提供线索，则优先选择 UTC，而非该时区的其他拼写。这修复了 tzdata 2019a 将 UCT 和 UTC 时区名设为等效后引入的不便：initdb 之前会优先选择几乎没有人想要的 UCT。

防止通过选择率估计器绕过行级安全策略（Dean Rasheed）

In CVE-2017-7484 we added restrictions to forestall that, but we failed to consider the effects of row-level security. A user who has SQL permission to read a column, but who is forbidden to see certain rows due to RLS policy, might still learn something about those rows' contents via a leaky operator.

默认在 fsync() 失败后触发 panic，而不重试，以避免可能的数据损坏（Craig Ringer，Thomas Munro）

\n

某些常见操作系统在无法写出内核数据缓冲区时会丢弃它们，并将其报告为 fsync() 失败。如果重新发出 fsync() 请求，它会成功，但实际上数据已丢失，因此继续运行有数据库损坏的风险。改为触发 panic 后，我们可以从 WAL 重放；在这种情况下，WAL 可能包含数据仅存的副本。虽然这种做法显然不够理想且效率低下，但替代方案很少，所幸这种情况极少发生。

\n

为控制此行为，添加了新的服务器参数data_sync_retry；如果确信内核不会在此类情况下丢弃脏数据缓冲区，可以将 data_sync_retry 设置为 on，恢复以前的行为。

修复 macOS 10.14（Mojave）上的构建问题（Tom Lane）

CVE-2023-2455 and CVE-2016-2193 fixed most interaction between row security and user ID changes. They missed cases where a subquery, WITH query, security invoker view, or SQL-language function references a table with a row-level security policy. This has the same consequences as the two earlier CVEs. That is to say, it leads to potentially incorrect policies being applied in cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs.\n\nApplying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects only databases that have used CREATE POLICY to define a row security policy. An attacker must tailor an attack to a particular application's pattern of query plan reuse, user ID changes, and role-specific row security policies.
