This will typically occur with deprecated or non-FIPS cipher algorithms (cipher-algo=blowfish/bf, twofish, cast5, or 3des). By default, pgcrypto will now fail to decrypt any messages that were affected in this way. To allow retrieval of such data, a new option ignore-cipher-failure has been added to pgp_pub_decrypt() and pgp_sym_decrypt(). Setting ignore-cipher-failure=1 will restore their previous behavior, allowing the faulty encryption wrapper to be stripped off: pgp_sym_decrypt(encrypted_column, any key, 'ignore-cipher-failure=1') Once the affected messages are identified and stripped of their wrappers, they can then be re-encrypted with a modern algorithm. It is important however that the behavior of OpenSSL be the same as it was when the faulty messages were created: if the set of unsupported algorithms is not the same, this approach will not work.

While this fix is unlikely to affect any production SQL scripts, test scripts might intentionally exercise failing COPY ... FROM STDIN commands.

\n许多规划器优化都会假定，例如，如果 x 上存在唯一索引，则最多只有一个表行能满足 WHERE x = 'abc'。不过，如果该索引和 WHERE 子句附加了不同的排序规则，一般来说这个结论是不安全的。当两个排序规则都是确定性排序规则时这是安全的，因为该属性本质上要求两个字符串相等就意味着逐位相等。但非确定性排序规则并不如此，因此如果 WHERE 子句或索引任一方具有非确定性排序规则，基于唯一匹配假设进行优化就可能给出错误的查询结果。

此修复防止了当后端进程吸收 NOTIFY 消息较慢时出现的 “could not access status of transaction” 错误。
将 NOTIFY 消息处理期间发生的错误升级为 FATAL，即关闭连接（Heikki Linnakangas）§
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。
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。
修复在锁定元组时跟踪更新链的错误（Jasper Smit）§
\n此代码路径忽略了检查更新链中第一个新元组的 xmin，使得在原始更新者中止且空间被 VACUUM 立即回收并重新使用的情况下，可能会锁定一个不相关的元组。这可能导致意外的事务延迟或死锁。与识别到错误元组相关的错误也已被观察到。

Two gaps in that protection have been found. One gap applies to partitioning and inheritance hierarchies where RLS policies on the tables should restrict access to statistics data, but did not. The other gap applies to cases where the query accesses a table via a view, and the view owner has permissions to read the underlying table but the calling user does not have permissions on the view. The view owner's permissions satisfied the security checks, and the leaky function would get applied to the underlying table's statistics before we check the calling user's permissions on the view.

However, it does not follow that the operating system user who executes psql to perform the restore should have to trust the source server. The risk here is that an attacker who has gained superuser-level control over the source server might be able to cause it to emit text that would be interpreted as psql meta-commands. That would provide shell-level access to the restoring user's own account, independently of access to the target database. To provide a positive guarantee that this can't happen, extend psql with a \\restrict command that prevents execution of further meta-commands, and teach pg_dump to issue that before any data coming from the source server.

If invalid characters are detected, they report an error if possible. For the ones that lack an error return convention, the output string is adjusted to ensure that the server will report invalid encoding and no intervening processing will be fooled by bytes that might happen to match single quote, backslash, etc. The purpose of this change is to guard against SQL-injection attacks that are possible if one of these functions is used to quote crafted input. There is no hazard when the resulting string is sent directly to a PostgreSQL server (which would check its encoding anyway), but there is a risk when it is passed through psql or other client-side code. Historically such code has not carefully vetted encoding, and in many cases it's not clear what it should do if it did detect such a problem. This fix is effective only if the data-quoting function, the server, and any intermediate processing agree on the character encoding that's being used. Applications that insert untrusted input into SQL commands should take special care to ensure that that's true. Applications and drivers that quote untrusted input without using these libpq functions may be at risk of similar problems. They should first confirm the data is valid in the encoding expected by the server. The PostgreSQL Project thanks Stephen Fewer for reporting this problem.

修复逻辑复制槽的 restart_lsn 可能后退的情况（Masahiko Sawada）§
之前，重启逻辑复制有时会导致复制槽的重启点被重新计算为一个比 pg_replication_slots 中先前公布值更旧的位置。这是有问题的，因为例如 WAL 文件可能已经根据较新的 restart_lsn 值被删除，在这种情况下复制将无法重启。
避免在 pg_rewind 过程中删除仍然需要的 WAL 文件（Polina Bungina，Alexander Kukushkin）§
\n之前，在不巧的情况下，pg_rewind 可能会从被回退的降级主库中删除重要的 WAL 文件。特别是当这些文件已经被标记为待归档（即其 .ready 文件已创建）但尚未归档时，就会发生这种情况。此时新提升的节点不再拥有这些文件，因为它们已经被回收，但降级节点的恢复可能需要它们。如果 pg_rewind 将它们删除，恢复就不再可能了。

\n如果被引用表是分区表，则独立的引用表与作为分区的引用表需要不同的目录条目。ATTACH/DETACH PARTITION 命令未能正确执行此转换。特别是在 DETACH 之后，现在独立的表将缺少外键强制触发器，这可能导致该表后来包含违反外键约束的行。随后的重新 ATTACH 也可能失败并产生令人意外的错误。
修复方法是对现在独立的表的每个有问题的约束执行 ALTER TABLE DROP CONSTRAINT，然后重新添加该约束。如果重新添加约束失败，说明已经有错误数据混入。需要手动恢复引用表和被引用表之间的一致性，然后重新添加约束。
以下查询可用于识别损坏的约束，并构造重建它们所需的命令：
\nSELECT conrelid::pg_catalog.regclass AS \"constrained table\",\n conname AS constraint,\n confrelid::pg_catalog.regclass AS \"references\",\n pg_catalog.format('ALTER TABLE %s DROP CONSTRAINT %I;',\n conrelid::pg_catalog.regclass, conname) AS \"drop\",\n pg_catalog.format('ALTER TABLE %s ADD CONSTRAINT %I %s;',\n conrelid::pg_catalog.regclass, conname,\n pg_catalog.pg_get_constraintdef(oid)) AS \"add\"\nFROM pg_catalog.pg_constraint c\nWHERE contype = 'f' AND conparentid = 0 AND\n (SELECT count(*) FROM pg_catalog.pg_constraint c2\n WHERE c2.conparentid = c.oid) <>\n ((SELECT count(*) FROM pg_catalog.pg_inherits i\n WHERE (i.inhparent = c.conrelid OR i.inhparent = c.confrelid) AND\n EXISTS (SELECT 1 FROM pg_catalog.pg_partitioned_table\n WHERE partrelid = i.inhparent)) +\n CASE WHEN pg_catalog.pg_partition_root(conrelid) = confrelid THEN\n (SELECT count(*) FROM pg_catalog.pg_partition_tree(confrelid)\n WHERE level = 1)\n ELSE 0 END);\n\n由于一个或多个 ADD CONSTRAINT 步骤可能会失败，应将查询输出保存到文件中，然后尝试执行每个步骤。

不要忽略正在处理带有谓词或表达式的索引的并发 REINDEX CONCURRENTLY（Michail Nikolaev）§
通常，REINDEX CONCURRENTLY 不需要等待其他表上的其他 REINDEX CONCURRENTLY 操作。但是，如果其他 REINDEX CONCURRENTLY 正在处理带有谓词或表达式的索引，则不应用此优化，因为这些表达式可能包含访问其他表的用户定义代码。粗心的编码造成了一个竞态条件，使得该规则未被统一应用，可能导致不一致的行为。
修复 EXPLAIN 中的 “failed to find plan for subquery/CTE” 错误（Richard Guo，Tom Lane）§ §
当试图打印子查询的 RECORD 类型输出的字段引用，而该子查询已从执行计划中完全优化掉时（至少在具有常量为假的 WHERE 条件时可能发生），就会出现这种情况。执行计划中不再有任何内容可以标识原始字段名，因此回退到对第 N 个记录列打印 f。（如果记录输出来自 NROW() 构造器，这实际上也是正确的做法。）
在更改生成列的类型时，禁止使用 USING 子句（Peter Eisentraut）§
生成列已经有一个指定列内容的表达式，因此包含 USING 没有意义。

\n此 tzdata 版本将旧的 System-V 兼容性区域名称更改为与对应地理区域重复；例如 PST8PDT 现在是 America/Los_Angeles 的别名。主要可见后果是，对于标准化时区引入之前的时间戳，该区域被认为代表命名位置的本地平均太阳时。例如，在 PST8PDT 中，timestamptz 输入如 1801-01-01 00:00 之前会被渲染为 1801-01-01 00:00:00-08，但现在会被渲染为 1801-01-01 00:00:00-07:52:58。
另外，包含墨西哥、蒙古和葡萄牙的历史修正。值得注意的是，Asia/Choibalsan 现在是 Asia/Ulaanbaatar 的别名而非独立区域，主要是因为这些区域之间的差异被发现是基于不可靠的数据。

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. Note that the attack is prevented only if both pg_dump and the server it is dumping from are new enough to have this fix. The PostgreSQL Project thanks Noah Misch for reporting this problem.

当分区表有一个不与约束关联的索引，但某个分区有一个等效的索引且该索引与约束关联时，分离该分区会出现异常行为，导致前分区的约束具有不正确的 coninhcount 值。这会在后续对该约束进行任何操作时引发问题。
修复 ALTER TABLE DETACH PARTITION CONCURRENTLY 期间的分区剪枝设置（Álvaro Herrera）§ §
执行器假定在对分区表的查询规划和执行之间不会有分区被分离。自从引入 DETACH PARTITION 的 CONCURRENTLY 选项后，这一假设不再成立，使得在使用该选项时查询执行可能会出现短暂的失败。
在最后一个子分区被删除后，正确地将分区表的 pg_class.reltuples 字段更新为零（Noah Misch）§
对这样的分区表进行第一次 ANALYZE 时必须同时更新 relhassubclass，而这导致 reltuples 的更新丢失。

修复从 CALL 语句的参数列表中调用稳定函数时的行为（Tom Lane）§
如果 CALL 位于原子上下文中（例如存在外部事务块），此类函数会被传递错误的快照，导致它们看到自外部事务开始以来已修改的行的过期值。

\n在展开目录元组的行外字段时发生的原地更新可能会被遗漏，导致目录缓存条目缺少原地更改但不被认为是过时的。这仅在 pg_database 目录中可能发生，因此影响范围较窄，但可能会导致异常行为。
正确检查由 INSERT ... DEFAULT 目标的视图列的可更新性（Tom Lane）§
如果这样的列不可更新，我们应该报告相应的错误。但该检查被遗漏了，随后的代码会报告一个不太有用的错误，如 “attribute number N not found in view targetlist”。

\n重新排列错误检查的顺序，以便在 WITH RECURSIVE 查询在 UNION 的第二个分支中没有自引用，但在其他位置（如 ORDER BY）有自引用时，抛出针对性的错误。
当排队的 AFTER 触发器不再存在时不抛出错误（Tom Lane）§
事务可能会执行一个操作将延迟的 AFTER 触发器排队等待后续执行，然后在触发器执行之前将其删除。之前这会导致诸如 “could not find trigger NNNN” 之类的奇怪错误。如果触发器在应该执行的时间点已不存在，静默地不做任何操作似乎更好。

PostgreSQL 项目感谢 Lukas Fittl 报告此问题。（CVE-2024-4317）
\n仅凭此修复本身只会修复新初始化的数据库集簇中的行为。如需在现有集簇中应用此更改，需要执行以下步骤：
\n在 PostgreSQL 安装的 share 目录（通常位于类似 /usr/share/postgresql/ 的位置）中找到 SQL 脚本 fix-CVE-2024-4317.sql。确保使用适合你的 PostgreSQL 主版本的脚本。如果未看到此文件，则说明你的版本不受影响（只有 v14–v16 受影响），或者你的小版本太旧，尚未包含此修复。
在集簇的每个数据库中，以超级用户身份运行 fix-CVE-2024-4317.sql 脚本。在 psql 中，命令如下：
\\i /usr/share/postgresql/fix-CVE-2024-4317.sql\n\n
（根据需要调整文件路径）。任何错误可能表明你使用了错误版本的脚本。多次运行该脚本不会有害。
\n不要忘记包含 template0 和 template1 数据库，否则以后创建的数据库仍然存在该漏洞。要修复 template0，你需要临时允许它接受连接。执行：
ALTER DATABASE template0 WITH ALLOW_CONNECTIONS true;\n\n
然后在修复 template0 后，执行以下命令撤销：
ALTER DATABASE template0 WITH ALLOW_CONNECTIONS false;\n\n

在 contrib/postgres_fdw 中，避免发出按常量排序的请求（David Rowley）§
这可能发生在涉及 UNION ALL 和常量输出子查询的情况下。按常量排序当然是无用的，但还有被远程服务器误解的风险，导致 “ORDER BY position N is not in select list” 错误。
使 contrib/postgres_fdw 将远程会话的时区设置为 GMT 而不是 UTC（Tom Lane）§
在实际用途中这应该产生相同的结果。然而，GMT 由服务器中的硬编码代码识别，而 UTC 则从时区数据库中查找。因此在远程服务器的时区数据库缺少条目的不太可能的情况下，旧代码可能失败。

避免在 to_tsvector() 处理长输入时过早的内存分配失败（Tom Lane）§
修复 tsvectorrecv() 中构造的 tsvector 的过度分配（Denis Erokhin）§
如果传入的向量包含位置数据，二进制接收函数会在完成的 tsvector 中留下浪费的空间（大约等于位置数据的大小）。在极端情况下，这可能导致对于发出时在长度限制内的向量产生 “maximum total lexeme length exceeded” 失败。无论如何都可能导致磁盘空间浪费。

避免在 system() 刚刚 fork 的子进程中对关闭信号的不当响应（Nathan Bossart）§ §
此修复避免了一个竞争条件：由 system() fork 出来但尚未 exec 目标子程序的子进程可能接收并处理原本发给父服务器进程的信号。这将导致重复的清理操作，后果不佳。
处理前端程序中 pg_control 的撕裂读取（Thomas Munro）§
在某些文件系统上，当服务器并发写入 pg_control 时，读取该文件可能不是原子操作。这可以通过无效的 CRC 来检测。现在在报告错误之前会重试几次以查看文件是否变为有效。
避免在相关 SQL 函数中对 pg_control 的撕裂读取（Thomas Munro）§
在读取 pg_control 之前获取适当的锁，以确保获得该文件的一致视图。
避免计算后端活动字符串数组大小时的整数溢出（Jakub Wartak）§
\n在 64 位机器上，我们允许 track_activity_query_size 的值大到足以在乘以允许的连接数时导致 32 位溢出。然而，实际分配每个后端本地数组的代码对此不够谨慎，导致数组分配不正确。

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。

修复 contrib/pg_trgm 在处理不可满足的正则表达式时的异常行为（Tom Lane）§
如 $foo 这样的正则表达式是合法的但不可满足；正则表达式编译器会识别到这一点并生成一个空的 NFA 图。尝试将这样的图优化为 pg_trgm GIN 或 GiST 索引限定条件时，会导致访问工作数组末尾之外的内容，可能导致崩溃。
在使用 GNU 兼容的 strip 剥离静态库时使用 --strip-unneeded 选项（Tom Lane）§
之前，make install-strip 在这种情况下使用 -x 选项。此更改避免了 llvm-strip 的异常行为，同时也能产生稍小的输出。

\n现在似乎不再可能在没有本地安装 DocBook DTD 文件的情况下构建 SGML 文档。之前 xsltproc 可以从 sourceforge.net 即时下载这些文件；但 sourceforge.net 现在只允许 HTTPS 访问，而没有常见版本的 xsltproc 支持该协议。因此，移除了我们文档中建议这种做法是可能或有用的部分，改为在构建配方中添加 xsltproc 的 --nonet 选项。

有一个惯例是 libpq 函数应检查 NULL 的 PGconn 参数，并优雅地失败而不是崩溃。PQflush() 和 PQisnonblocking() 没有遵循这个惯例，因此予以修复。
在 ecpg 中，修复在同一声明中声明多个 varchar 或 bytea 变量时遗漏变量存储类的问题（Andrey Sokolov）§
例如，ecpg 在翻译 static varchar str1[10], str2[20], str3[30]; 时，只有 str1 被标记为 static。
允许在 pg_basebackup 中进行跨平台表空间重定位（Robert Haas）§
\n允许 --tablespace-mapping 中的远程路径为 Unix 风格或 Windows 风格的绝对路径，因为源服务器可能与本地系统运行在不同的操作系统上。
在 pg_stat_statements 中，修复对已释放内存的访问（zhaoqigui）§
\n当 pg_stat_statements 跟踪通过扩展查询协议发出的 ROLLBACK 命令时会出现此问题。在调试构建中，这始终导致断言失败。在生产构建中，通常没有可见的不良影响；但如果释放的内存已经被重用，很可能的结果是存储查询字符串的垃圾数据。

uuid-ossp 模块期望 libc 的 uuid_create() 产生版本 1 的 UUID，但最近的 NetBSD 版本改为产生版本 4（随机）的 UUID。检查这一点，如果是则抛出错误。删除文档中关于 NetBSD 实现可用于 uuid-ossp 的声明。（如果版本 4 的 UUID 对你的目的来说没问题，你根本不需要 uuid-ossp；只需使用 gen_random_uuid() 即可。）

\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）。
对于运行 14.X 的用户，不需要执行导出/恢复。
\n但是，如果是从早于 14.4 的版本升级，请参见第 E.21 节。

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()。
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. All known callers of SPI_commit() immediately call SPI_start_transaction(), so they will not notice any change. Similar remarks apply to SPI_rollback().

在升级该操作符类以支持操作符类参数的过程中，ltree 列上 GiST 索引的默认签名长度（hash 大小）被意外更改了。如果在未先将 ltree 扩展升级到版本 1.2 的情况下对此类索引执行了任何操作，则这些操作假定签名长度为 28 字节，而非预期的 8 字节。这意味着此类索引很可能已经损坏。为了安全起见，我们建议在安装此更新后重建所有 ltree 列上的 GiST 索引。（注意，ltree[] 列上的 GiST 索引，即 ltree 数组，不受影响。）
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。
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。

修复 libpq 的 PQisBusy() 函数在连接失败后的行为（Tom Lane）§
如果检测到写入失败，PQisBusy() 总是返回 true，这是不正确的：我们希望输入处理继续正常进行，直到读取完服务器可用的所有内容。此错误的实际影响是，使用 libpq 异步查询 API 的应用程序通常只有在 PQconsumeInput() 返回硬失败时才能检测到连接丢失。通过此修复，连接丢失通常将通过错误 PGresult 对象报告，这对大多数应用程序来说是更清晰的行为。

v14 之前的版本会静默忽略包含多个点号的模式中除 schema 和 table 之外的所有部分。v14 中的重构意外地破坏了该用法。现在恢复了该功能，但如果第一部分不是当前数据库的名称，则会报错。

如果表还有至少两个大于 min_parallel_index_scan_size 阈值的索引，则并行 VACUUM 会无法处理低于该阈值的索引。这可能导致那些索引变得损坏，因为它们仍然包含对已被 VACUUM 移除的堆条目的引用；使用此类索引的后续查询可能会返回不应返回的行。此问题不影响 autovacuum，因为它不使用并行清理。但是，建议对具有合适索引大小组合的手动执行清理的表重建索引。
修复 CREATE INDEX CONCURRENTLY 以等待最新的预备事务（Andrey Borodin）§
刚刚预备的事务插入的行可能会从新索引中遗漏，导致依赖该索引的查询错过此类行。之前对此类问题的修复未能考虑到在 CREATE INDEX CONCURRENTLY 检查时仍在进行中的 PREPARE TRANSACTION 命令。与之前一样，在启用了预备事务（max_prepared_transactions > 0）的安装中，建议重建所有并发构建的索引，以防在构建时发生了此问题。
避免竞态条件导致后端无法将新行的条目添加到正在并发构建的索引中（Noah Misch，Andrey Borodin）§
\n虽然此情况在实际环境中似乎很少发生，但它可能影响使用 CONCURRENTLY 选项构建或重建的任何索引。建议重建此类索引以确保其正确性。

PostgreSQL is blocking this attack in the core server, so there's no need to modify individual extensions.\n\nThe PostgreSQL project thanks Sven Klemm for reporting this problem.", "first_published": "2022-08-11", "fixed_version": "14.5", "severity": "高危", "status_label": "目标版本已修复"}, {"id": "CVE-2026-6478", "url": "https://www.postgresql.org/support/security/CVE-2026-6478/", "fixed": {"14": "14.23", "15": "15.18", "16": "16.14", "17": "17.10", "18": "18.4"}, "score": 6.5, "title": "在认证代码中使用时序安全的字符串比较", "vector": "AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N", "cna_url": "https://cveawg.mitre.org/api/cve/CVE-2026-6478", "affected": {"14": "14", "15": "15", "16": "16", "17": "17", "18": "18"}, "component": "core server", "published": {"14": "2026-05-14", "15": "2026-05-14", "16": "2026-05-14", "17": "2026-05-14", "18": "2026-05-14"}, "introduced": {}, "cvss_version": "3.0", "description_en": "Covert timing channel in comparison of MD5-hashed password in PostgreSQL authentication allows an attacker to recover user credentials sufficient to authenticate.

For example, a non-core background worker that does not auto-restart would experience a denial of service with respect to that particular background worker.\n\nThe PostgreSQL project thanks Hemanth Sandrana and Mahendrakar Srinivasarao for reporting this problem.", "first_published": "2023-11-09", "fixed_version": "14.10", "severity": "低危", "status_label": "目标版本已修复"}], "cve_available": true, "security_regressions": [], "remaining_cves": [], "cross_major": false, "excluded_count": 0, "already_in_source_count": 0, "duplicate_count": 0, "candidate_count": 986, "exclusions": [], "history": {"source": ["9.0.0", "9.0.1", "9.0.2", "9.0.3", "9.0.4", "9.1.0", "9.1.1", "9.1.2", "9.1.3", "9.1.4", "9.1.5", "9.2.0", "9.2.1", "9.2.2", "9.2.3", "9.2.4", "9.3.0", "9.3.1", "9.3.2", "9.3.3", "9.3.4", "9.3.5", "9.4.0", "9.4.1", "9.4.2", "9.4.3", "9.4.4", "9.4.5", "9.5.0", "9.5.1", "9.5.2", "9.5.3", "9.5.4", "9.6.0", "9.6.1", "9.6.2", "9.6.3", "9.6.4", "9.6.5", "10.0", "10.1", "10.2", "10.3", "10.4", "10.5", "11.0", "11.1", "11.2", "11.3", "11.4", "11.5", "12.0", "12.1", "12.2", "12.3", "12.4", "13.0", "13.1", "13.2", "13.3", "13.4", "14.0"], "target": ["9.0.0", "9.0.1", "9.0.2", "9.0.3", "9.0.4", "9.1.0", "9.1.1", "9.1.2", "9.1.3", "9.1.4", "9.1.5", "9.2.0", "9.2.1", "9.2.2", "9.2.3", "9.2.4", "9.3.0", "9.3.1", "9.3.2", "9.3.3", "9.3.4", "9.3.5", "9.4.0", "9.4.1", "9.4.2", "9.4.3", "9.4.4", "9.4.5", "9.5.0", "9.5.1", "9.5.2", "9.5.3", "9.5.4", "9.6.0", "9.6.1", "9.6.2", "9.6.3", "9.6.4", "9.6.5", "10.0", "10.1", "10.2", "10.3", "10.4", "10.5", "11.0", "11.1", "11.2", "11.3", "11.4", "11.5", "12.0", "12.1", "12.2", "12.3", "12.4", "13.0", "13.1", "13.2", "13.3", "13.4", "14.0", "14.1", "14.2", "14.3", "14.4", "14.5", "14.6", "14.7", "14.8", "14.9", "14.10", "14.11", "14.12", "14.13", "14.14", "14.15", "14.16", "14.17", "14.18", "14.19", "14.20", "14.21", "14.22", "14.23", "14.24"], "candidates": ["14.1", "14.2", "14.3", "14.4", "14.5", "14.6", "14.7", "14.8", "14.9", "14.10", "14.11", "14.12", "14.13", "14.14", "14.15", "14.16", "14.17", "14.18", "14.19", "14.20", "14.21", "14.22", "14.23", "14.24"]}, "release_count": 24, "warnings": [], "source_as_of": "2026-09-26", "security_as_of": "2026-09-26"}
