在 Windows 的 libpq 中，每进程调用一次 WSAStartup()，完全不调用 WSACleanup()（Tom Lane、Alexander Lakhin）

\n

此前，libpq 在连接开始时调用 WSAStartup()，在连接清理时调用 WSACleanup()。然而，调用 WSACleanup() 似乎会干扰其他程序操作；特别是，我们观察到向 stdout 输出预期内容偶尔失败。省略该调用似乎没有不良影响，因此就这么做。（这还消除了程序执行一系列数据库连接时因反复加载和卸载 DLL 导致的性能问题。）

Since extensions often require superuser privilege to install, this can open a path to obtaining superuser privilege. To mitigate this risk, be more careful about the search_path used to run an installation script; disable check_function_bodies within the script; and fix catalog-adjustment queries used in some contrib modules to ensure they are secure.

避免使用 PAM 认证时记录关于废弃连接的抱怨（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把结果最后一字节中存在的填充空间清零。虽然对大多数操作不可见，但那里的任何非零位都会导致意外的比较行为，因为位串比较不会特意忽略多余的位，而是预期它们始终为零。

\n

如果你因把 bitshiftright() 的输出保存到表中而有不一致的数据，可以用类似下面的语句修复：

\n
UPDATE mytab SET bitcol = ~(~bitcol) WHERE bitcol != ~(~bitcol);\n

修复 pg_dump 对视图中循环依赖的处理（Tom Lane）

\n

某些情况下视图可能依赖于 pg_dump 需要在视图之后转储的对象；最常见的例子是在主键列上使用 GROUP BY 的查询在没有主键时可能在语义上无效。现在通过发出一个仅建立视图列名和类型的虚拟 CREATE VIEW 命令、之后再发出带完整视图定义的 CREATE OR REPLACE VIEW 来处理。此前虚拟定义实际上是一条 CREATE TABLE 命令，之后通过 CREATE RULE 命令自动转换成视图。这种新方法在 PostgreSQL 版本 10 及之后已经成功使用。现在把它向后移植到较旧的版本，是因为有报告称以前的方法会导致关于视图副本身份状态的虚假错误消息。这一更改还避免了在涉及此类视图的恢复期间尝试使用 --clean 选项时的问题。

This is now handled by emitting a dummy CREATE VIEW command that just establishes the view's column names and types, and then later emitting CREATE OR REPLACE VIEW with the full view definition. Previously, the dummy definition was actually a CREATE TABLE command, and this was automagically converted to a view by a later CREATE RULE command. The new approach has been used successfully in PostgreSQL version 10 and later. We are back-patching it into older releases now because of reports that the previous method causes bogus error messages about the view's replica identity status.

修复 contrib/intarray 的 GiST 操作符类在空数组使用 <@ 时不失败的问题（Tom Lane）

改进 initdb 对系统时区多个等价名称的处理（Tom Lane、Andrew Gierth）

\n

让 initdb 检查 /etc/localtime 符号链接（如果存在），以在系统时区的等价名称之间打破平局。这使 initdb 在存在多个相同时区时更可能选择用户期望的时区名。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，则不会改变行为。

\n

另外，当 TZ 和 /etc/localtime 都未提供提示时，优先选择 UTC 而不是该时区的其他拼法。这修复了 tzdata 2019a 把 UCT 和 UTC 时区名变为等价而引入的烦恼：initdb 随后偏爱 UCT，而几乎没人想要它。

A leaky operator therefore can disclose some of the entries in a data column, even if the calling user lacks permission to read that column. 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. This patch further tightens the rules, allowing leaky operators to be applied to statistics data only when there is no relevant RLS policy.

默认情况下，fsync() 失败后 panic 而不是重试，以避免可能的数据损坏（Craig Ringer、Thomas Munro）

\n

一些流行的操作系统在无法写出内核数据缓冲区时会将其丢弃，并把这报告为 fsync() 失败。如果我们重新发出 fsync() 请求它会成功，但实际上数据已经丢失，因此继续下去有数据库损坏的风险。通过引发 panic 条件，我们可以从 WAL 重放——这种情况下 WAL 中可能包含数据的唯一剩余副本。虽然这无疑丑陋且低效，但几乎没有其他选择，所幸这种情况很少发生。

\n

新增了服务器参数data_sync_retry来控制这一行为；如果你确定你的内核在此类场景下不会丢弃脏数据缓冲区，可以把 data_sync_retry 设为 on 恢复旧行为。

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

\n

调整 configure 向 CPPFLAGS 添加 -isysroot 开关；没有它，PL/Perl 和 PL/Tcl 在 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 的参数中设置 PG_SYSROOT 变量来覆盖。

\n

现在建议与 Perl 相关的扩展在其编译器标志中写 $(perl_includespec) 而不是 -I$(perl_archlibexp)/CORE。后者在大多数平台上继续有效，但在最近的 macOS 上不行。

允许 btree 比较函数返回 INT_MIN（Tom Lane）

到目前为止，我们禁止数据类型相关的比较函数返回 INT_MIN，这允许调用者只需对比较结果取反即可颠倒排序顺序。然而，对于直接返回 memcmp()、strcmp() 等结果的比较函数，这从来都不安全，因为 POSIX 没有对这些函数施加任何此类限制。至少某些最近版本的 memcmp() 可以返回 INT_MIN，导致错误的排序。因此我们移除了这一限制。调用者现在如果想颠倒排序顺序，必须使用 INVERT_COMPARE_RESULT() 宏。

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。

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.

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

ACL 归档条目的“标记”部分通常只是相关对象的名称。使它以对象类型开头，使 ACL 与注释和安全标签归档条目已使用的约定一致。同时修复整个数据库的注释和安全标签条目（如果存在），使其标记以 DATABASE 开头，从而也遵循这一约定。这防止试图通过查看标记是否以 LARGE OBJECT 开头来识别大对象相关条目的代码发生假匹配。那可能导致条目被错误分类为数据而非模式，在仅模式或仅数据转储中产生不希望的结果。

\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）

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
\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

    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

    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）

防止已过时的动态时区缩写失效（Tom Lane）

如果动态时区缩写与所引用时区中的任何条目都不匹配，就把它视为等效于该时区名称。这避免了当 IANA 从其时区数据库中移除缩写时出现意外失败——他们在 tzdata 2016f 版中就这样做过，而且将来可能再次这样做。后果不仅限于无法识别单个缩写；任何不匹配都会导致 pg_timezone_abbrevs 视图完全失败。

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）

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。

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。

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.

在非 C 区域设置中禁用字符串排序的缩写键（Robert Haas）

\n

PostgreSQL 9.5 引入了用标准 C 库函数 strxfrm() 替代 strcoll() 来加速字符串数据类型比较的逻辑。现在发现，大多数版本的 glibc（Linux 的 C 库实现）所实现的 strxfrm() 都有缺陷，在某些区域设置下会产生与 strcoll() 不一致的字符串比较结果。在更好地刻画此问题之前，在所有非 C 区域设置中禁用该优化。（C 区域设置是安全的，因为它既不使用 strcoll() 也不使用 strxfrm()。）

遗憾的是，此问题不仅影响排序，还影响 B-tree 索引中的条目排序，这意味着如果 text、varchar 或 char 列上的 B-tree 索引按受影响的区域设置排序，并且在 PostgreSQL 9.5.0 或 9.5.1 下构建或修改过，它们现在可能已经损坏。用户应对可能受影响的索引执行 REINDEX。

\n
