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

调整 configure 向 CPPFLAGS\n 添加 -isysroot 开关；没有它，PL/Perl 和 PL/Tcl 在\n macOS 10.14 上无法配置或构建。所用的具体 sysroot 可以在配置或构建时通过在 configure 或 make\n 的参数中设置 PG_SYSROOT 变量来覆盖。\n

修复连接尝试之间未能完全重置 libpq 状态的问题（Tom Lane）

修复少数内建函数上不正确的易变性标记（Thomas Munro、Tom Lane）

更改 ANALYZE 更新 pg_class.reltuples 的算法（David Gould）

\n

此前，ANALYZE 未实际扫描的页被假定保留其旧的元组密度。在 ANALYZE 只采样很少一部分页的大表中，这意味着总体元组密度估计不会有太大变化，因此无论表中实际发生什么，reltuples 都几乎与表物理大小（relpages）的变化成比例地变化。据观察，这会导致 reltuples 远大于实际值，以致实际上关闭了自动清理。为修复，假定 ANALYZE 的样本是表的无偏统计样本（本应如此），直接把这些页中观察到的密度外推到整表。

避免在 pg_dump 和其他客户端程序中使用不安全的 search_path 设置（Noah Misch、Tom Lane）

To make them secure whether or not the installation as a whole has been secured, modify them to include only the pg_catalog schema in their search_path settings. Autovacuum worker processes now do the same, as well. In cases where user-provided functions are indirectly executed by these programs — for example, user-provided functions in index expressions — the tighter search_path may result in errors, which will need to be corrected by adjusting those user-provided functions to not assume anything about what search path they are invoked under. That has always been good practice, but now it will be necessary for correct behavior.

为与未来次版本协议的前向兼容做准备（Robert Haas、Badrul Chowdhury）

到目前为止，PostgreSQL 服务器只是拒绝使用比 3.0 更新的协议版本的请求，因此协议版本号的主部分和次部分之间没有功能差别。允许客户端请求 3.x 版本而不失败，发回一条表明服务器只理解 3.0 的消息。这目前没有区别，但向后移植此更改应能更快引入未来的次协议升级。

修复 pg_dump 使 ACL（权限）、注释和安全标签条目在归档输出格式中可靠可识别（Tom Lane）

\n

进一步限制 pg_user_mappings.umoptions 的可见性，以保护存储为用户映射选项的密码（Noah Misch）

\n

CVE-2017-7486 的修复不正确：它允许用户看到她自己用户映射中的选项，即使她对相关外部服务器没有 USAGE 权限。这种选项可能包含由服务器所有者而非用户自己提供的密码。由于 information_schema.user_mapping_options 在这种情况下不显示选项，pg_user_mappings 也不应该。（CVE-2017-7547）

\n

此补丁本身只会修复新 initdb 的数据库中的行为。如果希望在现有数据库中应用此更改，需要执行以下操作：

\n
\n
    \n
  1. \n

    在 postgresql.conf 中添加 allow_system_table_mods = true 后重启 postmaster。（在支持 ALTER SYSTEM 的版本中，可以用它进行配置更改，但仍需重启。）

    \n
    2. \n
  2. \n

    在集簇的每个数据库中，以超级用户身份运行以下命令：

    \n
    SET search_path = pg_catalog;\nCREATE OR REPLACE VIEW pg_user_mappings AS\nSELECT U.oid AS umid, S.oid AS srvid, S.srvname AS srvname,\n       U.umuser AS umuser,\n       CASE WHEN U.umuser = 0 THEN 'public' ELSE A.rolname END AS usename,\n       CASE WHEN (U.umuser <> 0 AND A.rolname = current_user\n                   AND (pg_has_role(S.srvowner, 'USAGE')\n                        OR has_server_privilege(S.oid, 'USAGE')))\n                OR (U.umuser = 0 AND pg_has_role(S.srvowner, 'USAGE'))\n                OR (SELECT rolsuper FROM pg_authid WHERE rolname = current_user)\n            THEN U.umoptions ELSE NULL END AS umoptions\nFROM pg_user_mapping U\n     LEFT JOIN pg_authid A ON (A.oid = U.umuser)\n     JOIN pg_foreign_server S ON (U.umserver = S.oid);\n
    3. \n
  3. \n

    不要忘记包括 template0 和 template1 数据库，否则漏洞仍会存在于之后创建的数据库中。要修复 template0，需要暂时让它接受连接。在 PostgreSQL 9.5 及之后，可以使用

    \n
    ALTER DATABASE template0 WITH ALLOW_CONNECTIONS true;\n
    \n

    修复 template0 之后再撤销：

    \n
    ALTER DATABASE template0 WITH ALLOW_CONNECTIONS false;\n
    \n

    在更早的版本中，改用：

    \n
    UPDATE pg_database SET datallowconn = true WHERE datname = 'template0';\nUPDATE pg_database SET datallowconn = false WHERE datname = 'template0';\n
    4. \n
  4. \n

    最后，移除 allow_system_table_mods 配置设置，并再次重启 postmaster。

在 MSVC 构建中对 POSIX 风格时区名使用正确的夏令时规则（David Rowley）

\n

Microsoft MSVC 构建脚本忽略了把 posixrules 文件安装到时区目录树中。这导致时区代码回退到它内置的关于 POSIX 风格时区名应假定什么 DST 行为的规则。由于历史原因，那仍然对应美国 2007 年之前使用的 DST 规则（即 4 月第一个星期日和 10 月最后一个星期日更改）。有了此修复，POSIX 风格时区名将使用 US/Eastern 时区的当前和历史 DST 转换日期。如果不希望这样，移除 posixrules 文件，或用其他某个时区文件的副本替换它（见第 8.5.3 节）。注意由于缓存，可能需要重启服务器才能使这种更改生效。

修复客户端程序对数据库名和角色名中特殊字符的处理（Noah Misch、Nathan Bossart、Michael Paquier）

\n

vacuumdb 及其他客户端程序中的许多地方，可能会被包含双引号或反斜杠的数据库名和角色名弄混。收紧引用规则以使其安全。同时确保当 conninfo 字符串被用作这些程序的数据库名参数时，全程都被正确地如此对待。

\n

修复 psql 的 \\connect 和 \\password 命令中对成对双引号的处理，使其与文档一致。

\n

在 psql 的 \\connect 命令中引入新的 -reuse-previous 选项，以显式控制是否复用先前连接的连接参数。（若不使用该选项，则与以前一样，根据数据库名是否看起来像 conninfo 字符串来决定。）这使 pg_dumpall 脚本能够安全地处理包含特殊字符的数据库名。

\n

pg_dumpall 现在拒绝处理包含回车或换行的数据库名和角色名，因为在 Windows 上安全地引用这些字符似乎不切实际。将来我们可能会在服务器端拒绝此类名称，但尚未采取这一步骤。

Tighten up quoting rules to make that safe. Also, ensure that when a conninfo string is used as a database name parameter to these programs, it is correctly treated as such throughout. Fix handling of paired double quotes in psql's \\connect and \\password commands to match the documentation. Introduce a new -reuse-previous option in psql's \\connect command to allow explicit control of whether to re-use connection parameters from a previous connection. (Without this, the choice is based on whether the database name looks like a conninfo string, as before.) This allows secure handling of database names containing special characters in pg_dumpall scripts. pg_dumpall now refuses to deal with database and role names containing carriage returns or newlines, as it seems impractical to quote those characters safely on Windows. In future we may reject such names on the server side, but that step has not been taken yet. These are considered security fixes because crafted object names containing special characters could have been used to execute commands with superuser privileges the next time a superuser executes pg_dumpall or other routine maintenance operations.

修复新集群 TOAST 规则与旧集群不同时 pg_upgrade 失败的问题（Tom Lane）

修复pg_dump以转储 shell 类型（Tom Lane）

修复从不一致数据库状态恢复时可能失败的问题（Robert Haas）

\n

最近的PostgreSQL发行版引入了防御多事务 ID 回卷的机制，但其中一些代码没有考虑到可能需要在崩溃恢复期间（数据库可能不处于一致状态时）运行。这可能导致崩溃后无法重启或无法启动辅助服务器。在曾使用 9.3.0 到 9.3.4 之间pg_upgrade版本的安装中，pg_upgrade一个已修复缺陷的残留影响也可能导致这种失败。

\n

所涉及的pg_upgrade缺陷是：即使真实值应该更高，它也会把pg_control中的oldestMultiXid设为 1。有了本发行版引入的修复，这种情况将导致立即进行紧急自动清理，直到能够确定正确的oldestMultiXid值。如果这会造成困难，用户可以在升级到本发行版之前进行手工清理来避免。具体步骤如下：

\n
\n
    \n
  1. \n

    检查pg_controldata报告的“Latest checkpoint's oldestMultiXid”是否为 1。如果不是，则无需任何操作。

    \n
    2. \n
  2. \n

    查看PGDATA/pg_multixact/offsets中是否有名为0000的文件。如果有，则无需任何操作。

    \n
    3. \n
  3. \n

    否则，对于 pg_class.relminmxid 等于 1 的每个表，在把vacuum_multixact_freeze_min_age和vacuum_multixact_freeze_table_age都设为零的情况下对该表执行 VACUUM。（可以使用第 18.4.4 节中描述的清理代价延迟参数，来降低对并发会话的性能影响。）执行这一步必须使用 PostgreSQL 9.3.5 或更高版本。

The lingering effects of a previously-fixed bug in pg_upgrade could also cause such a failure, in installations that had used pg_upgrade versions between 9.3.0 and 9.3.4.

With the fixes introduced in this release, such a situation will result in immediate emergency autovacuuming until a correct oldestMultiXid value can be determined. If that would pose a hardship, users can avoid it by doing manual vacuuming before upgrading to this release.

修复罕见的未能使关系缓存 init 文件失效的问题（Tom Lane）

避免崩溃重启期间对数据目录执行fsync时失败（Abhijit Menon-Sen、Tom Lane）

修复contrib/citext的regexp_matches()函数的错误声明（Tom Lane）

这段应急代码于 2003 年添加，起因是当时的某些 Linux 内核会把 IPv4 连接报告为 IPv4-in-IPv6 地址。然而该逻辑在 9.0 中被意外破坏。此后没有任何现场投诉，说明它已不再需要。现在反而有报告称被破坏的代码在某些系统上导致崩溃，因此我们选择直接移除而不是修复它。（如果选择修复，将会使 IPv4 pg_hba.conf 条目的实际含义发生微妙且可能涉及安全性的变化，在次版本中这样做似乎并不妥当。）

修复出错后前端/后端协议可能失去同步的问题（Heikki Linnakangas）

\n

如果服务器在从客户端读取协议消息中途发生任何错误，它可能失去同步，错误地把消息数据的一部分解释为新的协议消息。能够在命令参数中提交恶意构造二进制数据的攻击者可能借此注入自己的 SQL 命令。语句超时和查询取消是触发此场景最可能的错误来源。尤其容易受影响的是既使用超时又将任意用户构造数据作为二进制查询参数提交的应用程序。禁用语句超时会降低但不能消除被利用的风险。感谢 Emil Lenngren 报告此问题。（CVE-2015-0244）

修复 psql 的 \\s 命令，使其与 libedit 良好配合，并新增分页器支持（Stepan Rutz、Tom Lane）

\n

使用 libedit 而非 readline 时，\\s 会以一种相当难读的编码格式打印命令历史，而且在较新的 libedit 版本上可能完全失败。现已改为由我们自己打印历史而不是让库来做。一个令人愉快的副作用是，在合适的时候会使用分页器。

\n

此补丁还修复了一个在使用 libedit 保存命令历史时换行编码不一致的缺陷。旧版 psql 写出的多行历史条目在此补丁后可以干净地读取，但反过来未必可行，具体取决于所涉及的 libedit 版本。

保护 make check 期间启动的临时 postmaster 的 Unix 域套接字（Noah Misch）

\n

正如我们此前在 CVE-2014-0067 中指出的，任何能够访问套接字文件的本地用户都可以以服务器的引导超级用户身份连接，进而以运行测试的操作系统用户身份执行任意代码。此变更通过把服务器的套接字放到 /tmp 下一个临时的、模式为 0700 的子目录中来防御这一风险。但在不支持 Unix 套接字的平台（尤其是 Windows）上风险仍然存在，因为那时临时 postmaster 必须接受本地 TCP 连接。

不过，本版本纠正的若干问题可能已经导致外键约束损坏；也就是说，现在可能存在在被引用表中没有匹配行的引用行。在安装此更新后，重新检查这类约束可能是值得的。最简单的方法是删除并重建每个可疑约束；但这需要对两个表都加排他锁，因此在生产数据库中不太可能被接受。另一种办法是对两个表手工执行连接查询来查找不匹配的行。

如果某行被事务 A 锁定，而事务 B 更新了它，B 创建的新行版本会被 A 锁定，却只对 B 可见。如果事务 B 随后再次更新该行，A 的锁不会被检查，从而可能允许 B 在不该完成时完成。这种情况是 9.3 新出现的，因为之前的版本没有任何允许其他事务更新被锁行的行锁类型。

\n

这一疏忽可能导致引用完整性检查给出假阳性（例如允许本应被拒绝的删除）。使用新命令 SELECT FOR KEY SHARE 和 SELECT FOR NO KEY UPDATE 的应用也可能遭遇此类锁失效。

修复 VACUUM 判断是否可以更新 relfrozenxid 的测试（Andres Freund）

\n

某些情况下，VACUUM（手工或自动）可能错误地推进表的 relfrozenxid 值，使元组逃过冻结，导致这些行在经过 2^31 个事务后变得不可见。由于需要多次错误推进才会发生实际丢失，数据丢失的概率相当低，但并非为零。在 9.2.0 及更高版本中，丢失概率更高，而且这一缺陷还可能导致 “could not access status of transaction” 错误。从 9.0.4、8.4.8 或更早版本升级的用户不受影响，但之后的所有版本都包含该缺陷。

\n

升级后，在把 vacuum_freeze_table_age 设为零的情况下对所有数据库中的所有表执行清理，可以缓解此问题。这会修复任何潜伏的损坏，但无法修复所有既有的数据错误。不过，如果安装在其生命周期内执行的事务少于 2^31 个更新（可用 SELECT txid_current() < 2^31 检查），则在执行此清理之后即可认为该安装是安全的。
