ALTER COLUMN TYPE are hazardous because tuples of the older row layout may still exist in the system. While we have long had some checks to defend against that, they were never really complete, and they entirely failed to detect cases where composite types were changed concurrently with queries using them. This voluminous set of patches attempts to improve that. Introduce versioning logic to permit detection of composite datums that don't match the tuple descriptor we wish to interpret them with. For full protection, this change requires rebuilding C-language extensions, and there are some extensions that will require source-code changes. If necessary, the new composite_type_mismatch server parameter can be used to disable these checks, but doing so carries security risks. Add locking to prevent cases such as ALTER TYPE on a composite type used in a CREATE TABLE that hasn't committed yet. Tighten the rules about whether ALTER COLUMN TYPE is allowed when dependencies exist on the composite type. For example, it's no longer allowed when a function's default expression or new-style SQL function body depends on the type.

This patch disables de-duplication for new index entries, but does nothing about possible corruption of existing entries.

This is a significant change that normally we'd never consider back-patching, but the prospect of continuing bugs from the old implementation has driven us to take the risk of doing so.", "commit_aliases": ["00d1b4598", "051db7737", "0ab90a5c9", "0c45929db", "1000f7b14", "12f10c25c", "13466d1f7", "18aca7257", "197a41aa6", "22a8f5339", "2d48d0f15", "2ebf25e7d", "37b6e2657", "37c2bc950", "38fe5a936", "3bfc7c849", "4264a1748", "476b9eb3c", "51f9e30f3", "533915857", "54ac06f31", "6b3f8857a", "6b858a36d", "763d563ea", "78d07020b", "83bd1c1ba", "8bcb6f901", "8ea97ee34", "91b1872ff", "986870baa", "9df23331f", "9f25197bf", "a8bb1a777", "ad4b80b6f", "bd003dca0", "bee81f786", "c04649d1d", "ccb7d9dba", "d15ab66f5", "dca6a9e32", "e28cf96e9", "e509be9ce", "fc8ed6362"], "source_commits": ["00d1b4598", "1000f7b14", "12f10c25c", "13466d1f7", "197a41aa6", "51f9e30f3", "bd003dca0", "ccb7d9dba", "dca6a9e32"], "source_entry_id": "17.12/changes/054", "db_id": "b5b80d3c819492e1c08b8f51828aa882", "patch_ids": ["021b1bdf4de69ec6a9e7a971fe7f7aad", "10c2da903db6a2d5e76f7e3e0c19225c", "1b9e65bae7085a97c590f5d178c5ddc5", "381bb4db6d4236dbd24248e719e873ca", "6196d3161709faf303595df55fca4fde", "728b29e7c9d3e0e689faf0c5e06515f2", "80b7028bbeab1b8e15062aaa3f3a07d9", "f7281b2dddaf84bb616d135debb8cae6", "fcd9704eb870e66b3f18b047bd2d7794"], "statement_hash": "a535e5adaafc9e558c036740f85cbcf5f60cb9bc1bedd95ac284c9282e8268ed", "relations": [{"rule": 2, "type": "equivalent", "target": "cb1594eaa56ee96a95bdf14bcf9d91ef", "evidence": {"same_day": true, "patch_ids": ["021b1bdf4de69ec6a9e7a971fe7f7aad", "10c2da903db6a2d5e76f7e3e0c19225c", "1b9e65bae7085a97c590f5d178c5ddc5", "381bb4db6d4236dbd24248e719e873ca", "6196d3161709faf303595df55fca4fde", "728b29e7c9d3e0e689faf0c5e06515f2", "80b7028bbeab1b8e15062aaa3f3a07d9", "f7281b2dddaf84bb616d135debb8cae6", "fcd9704eb870e66b3f18b047bd2d7794"], "statement_hash": "a535e5adaafc9e558c036740f85cbcf5f60cb9bc1bedd95ac284c9282e8268ed"}}, {"rule": 2, "type": "equivalent", "target": "dd1790e4961d9a6fa4d5b25bc71f63d1", "evidence": {"same_day": true, "patch_ids": ["021b1bdf4de69ec6a9e7a971fe7f7aad", "10c2da903db6a2d5e76f7e3e0c19225c", "1b9e65bae7085a97c590f5d178c5ddc5", "381bb4db6d4236dbd24248e719e873ca", "6196d3161709faf303595df55fca4fde", "728b29e7c9d3e0e689faf0c5e06515f2", "80b7028bbeab1b8e15062aaa3f3a07d9", "f7281b2dddaf84bb616d135debb8cae6", "fcd9704eb870e66b3f18b047bd2d7794"], "statement_hash": "a535e5adaafc9e558c036740f85cbcf5f60cb9bc1bedd95ac284c9282e8268ed"}}], "version": "17.12", "category_label": "BUG 修复", "also_in": [], "variants": [], "related_changes": [{"db_id": "cb1594eaa56ee96a95bdf14bcf9d91ef", "kind": "equivalent", "version": "18.7", "label": "18.7", "title": "通过修改查询的语法解析树来移除连接，而不再尝试修补规划器衍生的数据结构", "evidence": {"same_day": true, "patch_ids": ["021b1bdf4de69ec6a9e7a971fe7f7aad", "10c2da903db6a2d5e76f7e3e0c19225c", "1b9e65bae7085a97c590f5d178c5ddc5", "381bb4db6d4236dbd24248e719e873ca", "6196d3161709faf303595df55fca4fde", "728b29e7c9d3e0e689faf0c5e06515f2", "80b7028bbeab1b8e15062aaa3f3a07d9", "f7281b2dddaf84bb616d135debb8cae6", "fcd9704eb870e66b3f18b047bd2d7794"], "statement_hash": "a535e5adaafc9e558c036740f85cbcf5f60cb9bc1bedd95ac284c9282e8268ed"}, "url": "/docs/compare/?release=18.7#18.7-9e1ce1eb695d1cf6", "source_url": "/docs/release/18.7/#RELEASE-18-7-CHANGES"}, {"db_id": "dd1790e4961d9a6fa4d5b25bc71f63d1", "kind": "equivalent", "version": "16.16", "label": "16.16", "title": "通过修改查询的语法解析树来移除连接，而不再尝试修补规划器衍生的数据结构", "evidence": {"same_day": true, "patch_ids": ["021b1bdf4de69ec6a9e7a971fe7f7aad", "10c2da903db6a2d5e76f7e3e0c19225c", "1b9e65bae7085a97c590f5d178c5ddc5", "381bb4db6d4236dbd24248e719e873ca", "6196d3161709faf303595df55fca4fde", "728b29e7c9d3e0e689faf0c5e06515f2", "80b7028bbeab1b8e15062aaa3f3a07d9", "f7281b2dddaf84bb616d135debb8cae6", "fcd9704eb870e66b3f18b047bd2d7794"], "statement_hash": "a535e5adaafc9e558c036740f85cbcf5f60cb9bc1bedd95ac284c9282e8268ed"}, "url": "/docs/compare/?release=16.16#16.16-fedc0a5d339eab64", "source_url": "/docs/release/16.16/#RELEASE-16-16-CHANGES"}]}, {"id": "17.12-7bb9d1a4b6385bf8", "cves": [], "html": "

将逻辑解码输出插件限制为新服务器参数 output_plugin_libraries 指定的集合（Jacob Champion）§ §

\n

此前，复制用户可以为逻辑解码选择任意可加载库，从而实施各种攻击。为了在不破坏原有可用配置的情况下收紧这一限制，现引入一份允许使用的输出插件列表。

\n

默认情况下，只有随 PostgreSQL 提供的输出插件（pgoutput 和 test_decoding）会包含在 output_plugin_libraries 中。使用其他输出插件的安装必须在更新服务器后将其加入该参数，例如：

\n
output_plugin_libraries = 'pgoutput, test_decoding, my_trusted_decoder'\n
\n

此外，从版本 17 或更高版本迁移时，如果 pg_upgrade --check 发现新集簇的 output_plugin_libraries 参数不允许旧集簇逻辑复制槽所使用的插件，检查将会失败。请在执行 pg_upgrade 前对新集簇的设置作必要补充。

修复 contrib/pgcrypto 的 PGP 加密，使其能够检测不受支持的密码算法（Daniel Gustafsson）§ §

\n

此前，如果 OpenSSL 拒绝所请求的密码算法（例如，因为它正以 FIPS 模式运行，或尚未加载 legacy provider），pgcrypto 无法发现这一失败，只会将未经加密的块与明文进行异或，使这种“加密”轻易即可破解。这通常发生在已弃用或不符合 FIPS 的密码算法上（cipher-algo=blowfish/bf、twofish、cast5 或 3des）。

\n

默认情况下，pgcrypto 现在将无法解密以这种方式受影响的任何消息。为了能够取回这类数据，现新增选项 ignore-cipher-failure，用于 pgp_pub_decrypt() 和 pgp_sym_decrypt()。设置 ignore-cipher-failure=1 将恢复此前的行为，从而可以移除有缺陷的加密封装：

\n
pgp_sym_decrypt(encrypted_column, any key, 'ignore-cipher-failure=1')\n
\n

识别出受影响的消息并移除其封装后，即可使用现代算法重新加密。不过，OpenSSL 的行为必须与创建这些有缺陷消息时相同：如果不受支持的算法集合并不相同，这种方法将无法奏效。请参阅 ignore-cipher-failure 的文档。

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.

将 PQfn() 标记为不安全，并避免在 libpq 内部使用它（Nathan Bossart）§

\n

对于非整数结果类型，PQfn() 不会获得输出缓冲区的大小，因此它无法检查服务器返回的数据能否放入缓冲区。恶意服务器因而可能覆盖客户端内存。若不改变 API 就无法修复这一点，所以将该函数标记为已废弃。在 libpq 内部，改用一个能够执行缺失检查的变体版本。

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。

Depending on the application logic, missing a notification could cause the application to get stuck waiting, for example.

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

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。

修复在有多个扫描条件的 GIN 索引扫描中可能出现的无限循环（Tom Lane）§

GIN 可以处理能够拒绝不匹配条目但不适用于搜索相关条目的扫描条件，例如 tsquery 子句如 !term。但此类条件不能排在扫描条件数组的第一个位置。代码在所有情况下都未能确保这一点，导致包含此类条件与正常条件混合的查询可能根据查询中条件给出的顺序不同而正常工作或不工作。

加强规划器估算函数中的安全检查（Dean Rasheed）§

\n

针对 CVE-2017-7484 的修复及后续修复，旨在防止泄漏函数被应用于调用用户无权读取的列的统计数据。在该保护措施中发现了两个漏洞。其中一个漏洞适用于分区和继承层次结构，其中表上的 RLS 策略应当限制对统计数据的访问，但实际上并未限制。

\n

另一个漏洞适用于查询通过视图访问表的情况，其中视图所有者有权读取底层表，但调用用户没有视图的权限。视图所有者的权限满足了安全检查，而泄漏函数会在我们检查调用用户对视图的权限之前就被应用于底层表的统计数据。此问题已通过在规划开始时对视图进行安全检查来修复。这可能会导致权限错误比之前更早发生。

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. This has been fixed by making security checks on views occur at the start of planning. That might cause permissions failures to occur earlier than before.

防止 pg_dump 脚本被用于攻击执行恢复的用户（Nathan Bossart）§

\n

由于导出/恢复操作通常涉及以超级用户身份运行 SQL 命令，目标数据库安装必须信任源服务器。然而，这并不意味着执行 psql 进行恢复的操作系统用户也需要信任源服务器。这里的风险是，已获得源服务器超级用户级别控制权的攻击者可能会使其生成被解释为 psql 元命令的文本。这将提供对恢复用户自身帐户的 shell 级别访问，独立于对目标数据库的访问。

为了提供确保不会发生此问题的正面保证，扩展了 psql，增加了 \\restrict 命令来阻止执行后续的元命令，并让 pg_dump 在来自源服务器的任何数据之前发出该命令。

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.

我们上一轮次版本发布中包含了一项修复，确保复制接收进程会响应跨进程缓存失效消息，从而避免它们在执行复制更新时使用过期的系统目录数据。然而，该修复无意中也让这些进程再次重新分发这些消息，导致失效消息数量呈指数级增长，并且常常以内存分配失败告终。现已通过不重新分发收到的消息来修复该问题。

避免在 brin_bloom_union() 中合并压缩的 BRIN 摘要时丢失数据（Tomas Vondra）§

该代码未能考虑到解压缩结果与输入对象不完全相同的情况，这会导致未能将部分数据添加到合并后的摘要中，从而在索引搜索中遗漏行。

\n

这个错误从引入 BRIN bloom 索引的 v14 就存在了，但当时这个代码路径很少被触及。在 v17 中由于并行索引构建现在使用了该代码，因此更容易被触发。

加强 PQescapeString 及相关函数对无效编码输入字符串的防护（Andres Freund，Noah Misch）§ § § § § §

\n

libpq 提供的数据引用函数现在会完全检查其输入的编码有效性。如果检测到无效字符，会尽可能报告错误。对于缺少错误返回机制的函数，输出字符串会被调整以确保服务器会报告无效编码，并且中间处理不会被恰好匹配单引号、反斜杠等的字节所欺骗。

\n

此变更的目的是防范在使用这些函数对精心构造的输入进行引用时可能发生的 SQL 注入攻击。当结果字符串直接发送到 PostgreSQL 服务器时没有风险（服务器无论如何都会检查编码），但当它通过 psql 或其他客户端代码传递时存在风险。历史上此类代码未仔细审查编码，在许多情况下如果检测到此类问题也不清楚应该怎么做。

\n

此修复仅在数据引用函数、服务器以及任何中间处理对所使用的字符编码达成一致时才有效。插入不可信输入到 SQL 命令中的应用程序应特别注意确保这一点。

\n

不使用这些 libpq 函数而引用不可信输入的应用程序和驱动程序可能面临类似问题的风险。它们应首先确认数据在服务器期望的编码中是有效的。

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.

将并行工作进程排除在连接权限检查和限制之外（Tom Lane）§

启动并行工作进程时不再检查 datallowconn、rolcanlogin 和 ACL_CONNECT 权限，而是假定领导进程最初通过了类似检查就足够了。这避免了例如当领导进程以缺少登录权限的角色运行时，并行化查询出现意外失败的情况。同样，ReservedConnections、datconnlimit 和 rolconnlimit 限制仅对普通后端执行，且仅计算普通后端的数量来检查是否已达到限制。这些限制旨在防止普通后端过度占用进程槽位——而并行工作进程和其他特殊进程有自己的进程槽池和自己的限制检查。

修复关系截断失败时的数据损坏问题（Thomas Munro）§ § §

执行关系截断所需的文件系统调用可能会失败，导致磁盘上留下不一致的状态（例如，实际上恢复了已删除的数据）。我们无法真正阻止这种情况，但可以通过将此类失败提升为 PANIC 来进行恢复，这样可以通过从 WAL 重放到尝试截断之前来恢复一致性。这并不是一个非常理想的行为，但由于此类失败足够罕见，因此似乎是一个可以接受的解决方案。

在 contrib/earthdistance 的 SQL 语言函数声明中使用 SQL 标准函数体（Tom Lane，Ronan Dunklau）§

此变更允许在扩展创建期间解析其对 contrib/cube 的引用，降低了基于搜索路径的失败和可能攻击的风险。

确保当 RLS 应用于非顶级表引用时，缓存的执行计划被标记为依赖于调用角色（Nathan Bossart）§

如果查询中的 CTE、子查询、子链接、安全调用者视图或强制类型转换投影引用了具有行级安全策略的表，我们忽略了将结果执行计划标记为可能依赖于执行它的角色。这可能导致同一会话中后续的查询执行使用错误的执行计划，然后返回或隐藏本应被隐藏或返回的行。

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

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）§ §

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。

修复在附加或分离表分区时外键约束的目录状态更新（Jehan-Guillaume de Rorthais，Tender Wang，Álvaro Herrera）§ §

\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。

\n

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。

\n
