\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。

修复在一条命令中更改多列类型时 ALTER TABLE ... ALTER COLUMN TYPE 的失败（Tom Lane）
这修复了最近几个小版本中引入的回归：使用被更改列的索引未被正确处理，导致 ALTER TABLE 期间的奇怪失败。

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。

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。
修复共享失效消息处理中的递归风险（Tom Lane）
\n这个错误可能导致例如无法访问刚被 VACUUM FULL 处理过的系统目录或索引。
这一更改给 LockAcquire 添加了新的结果码，可能影响该函数的外部调用者，尽管只有非常不寻常的使用模式才会有问题。LockAcquireExtended 的 API 也有更改。

\ndblink 或 postgres_fdw 的无权限用户可以绕过旨在防止使用服务器端凭据（如运行服务器的操作系统用户拥有的 ~/.pgpass 文件）的检查。允许本地连接上对等认证的服务器尤其容易受影响。其他攻击（如向 postgres_fdw 会话注入 SQL）也是可能的。以这种方式攻击 postgres_fdw 需要能够创建带选定连接参数的外部服务器对象，但任何能访问 dblink 的用户都可以利用该问题。一般而言，能够为使用 libpq 的应用选择连接参数的攻击者都可能作恶，尽管其他合理的攻击场景更难想到。感谢 Andrew Krasichkov 报告此问题。（CVE-2018-10915）

过于乐观的缓存规则可能阻止其他会话看到这些更新，导致虚假错误和/或数据损坏。对于 pg_authid 等共享目录，问题明显更严重，因为过期的缓存数据不仅存在于现有会话，还会持续到新会话中。

向 ecpg 的 pgtypes 库添加字符串释放函数，以避免 Windows 上的跨模块内存管理问题（Takayuki Tsunakawa）
在 Windows 上，如果给定内存块的 free 调用不是来自 malloc 该内存的同一 DLL，就会发生崩溃。pgtypes 库有时返回期望调用者释放的字符串，使得无法遵循这一规则。添加了仅包装 free 的 PGTYPESchar_free() 函数，允许应用遵循规则。

\n函数 query_to_xml、cursor_to_xml、cursor_to_xmlschema、query_to_xmlschema 和 query_to_xml_and_xmlschema 应标记为 volatile，因为它们执行可能包含易变操作的用户提供的查询。它们没有被这样标记，导致错误查询优化的风险。新安装已通过更正初始目录数据修复，但现有安装将继续包含错误标记。实际使用这些函数似乎危害不大，但如遇到麻烦，可以手动更新这些函数的 pg_proc 条目来修复，例如 ALTER FUNCTION pg_catalog.query_to_xml(text, boolean, boolean, text) VOLATILE。（注意安装中的每个数据库都需要这样做。）另一个选择是把数据库 pg_upgrade 到包含更正后初始数据的版本。
避免重用与已死但尚未清理的 TOAST 条目匹配的 TOAST 值 OID（Pavan Deolasee）
\n一旦 OID 计数器回卷，就可能分配一个 OID 与同一 TOAST 表中先前删除的条目匹配的 TOAST 值。如果该条目尚未被清理，就会导致 “unexpected chunk number 0 (expected 1) for toast value nnnnn” 错误，并持续到 VACUUM 移除死条目为止。修复方法是创建新 TOAST 条目时不选择这种 OID。
更改 ANALYZE 更新 pg_class.reltuples 的算法（David Gould）
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 SERIALIZABLE 或 REPEATABLE READ 事务隔离下运行的并发 CREATE INDEX CONCURRENTLY 命令中的死锁（Tom Lane）

In particular, there was a discrepancy in the interpretation of a negative third parameter: Oracle thinks that a negative value indicates the last place where the target substring can begin, whereas our functions took it as the last place where the target can end. Also, Oracle throws an error for a zero or negative fourth parameter, whereas our functions returned zero. The sample code has been adjusted to match Oracle's behavior more precisely.

改进 Windows 上 PL/Perl 编译器标志的选择（Tom Lane）
\n此修复避免了因对 time_t 值宽度的假定不一致而可能的 PL/Perl 崩溃。扩展开发者可能看到的一个副作用是 _USE_32BIT_TIME_T 不再在 PostgreSQL Windows 构建中全局定义。这预计不会引起问题，因为 time_t 类型没有用于任何 PostgreSQL API 定义。
对于运行 9.4.X 的用户，不需要转储/恢复。
\n但是，如果你使用的外部数据服务器依赖用户密码进行认证，请参见下面的第一条变更日志条目。
\n另外，如果你是从早于 9.4.12 的版本升级，请参见第 E.15 节。

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）
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。）
在集簇的每个数据库中，以超级用户身份运行以下命令：
\nSET 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
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
ALTER DATABASE template0 WITH ALLOW_CONNECTIONS true;\n\n
修复 template0 之后再撤销：
ALTER DATABASE template0 WITH ALLOW_CONNECTIONS false;\n\n
在更早的版本中，改用：
\nUPDATE 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。
禁止在所有基于密码的认证方法中使用空密码（Heikki Linnakangas）
\nlibpq 忽略空的密码说明，不把它们传输给服务器。因此，如果用户的密码被设为空字符串，就无法通过 psql 或其他基于 libpq 的客户端用该密码登录。管理员可能因此认为把密码设为空等同于禁用密码登录。然而，使用修改过的或非 libpq 的客户端，登录可能是可能的，这取决于配置的认证方法。特别是最常见的方法 md5 接受空密码。更改服务器在所有情况下拒绝空密码。（CVE-2017-7546）
让 lo_put() 检查对目标大对象的 UPDATE 权限（Tom Lane、Michael Paquier）
