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。

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。

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.

修复关系插入关系缓存“init 文件”的问题（Tom Lane）

\n

最近几个小版本中一个补丁的疏忽导致pg_trigger_tgrelid_tgname_index被遗漏在 init 文件之外。后续会话检测到这一点后认定 init 文件已损坏并静默忽略它，导致会话启动时间显著退化。除修复该缺陷外，还加入了一些防护，使未来任何类似错误更明显。

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

这些函数应当像它们所包装的核心函数一样返回setof text[]；但它们被错误地声明为只返回text[]。这一错误有两个后果：第一，如果没有匹配，得到的是标量 null 结果，而正确的应该是空集（零行）。第二，g标志实际上被忽略了，因为即使有多个匹配也只会得到一个结果数组。

修复替换实现的*printf()函数中的缓冲区越界（Tom Lane）

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

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

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。

把时区数据文件更新为 tzdata 版本 2015a。

IANA 时区数据库为所有澳大利亚时区采用了 AxST/AxDT 形式的缩写，以反映他们认为的当地当前多数用法。这些名称与其他地方的用法不冲突（唯一例外是表示 Acre 夏令时的 ACST，该用法自 1994 年起已废弃）。因此，我们把这些名称采纳进“默认”时区缩写集。“澳大利亚”缩写集现在只包含 CST、EAST、EST、SAST、SAT 和 WST，这些被认为主要是历史用法。注意，在“默认”缩写集中，SAST 也已改为南非标准时间。

\n

此外，新增时区缩写 SRET（Asia/Srednekolymsk）和 XJT（Asia/Urumqi），并对西萨摩亚使用 WSST/WSDT。同时，智利、墨西哥、特克斯和凯科斯群岛（America/Grand_Turk）以及斐济的夏令时法规有变更。还为巴布亚新几内亚部分地区新增了时区 Pacific/Bougainville。另外还有大量针对历史（1970 年以前）时区数据的修正。

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

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。

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。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。

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。

Users upgrading from releases 9.0.4 or 8.4.8 or earlier are not affected, but all later versions contain the bug. The issue can be ameliorated by, after upgrading, vacuuming all tables in all databases while having vacuum_freeze_table_age set to zero. This will fix any latent corruption but will not be able to fix all pre-existing data errors.

修复 WAL 重放期间共享缓冲区的持久性标记（Jeff Davis）

\n

这一失误可能导致缓冲区在检查点期间未被写出，如果服务器之后在这些缓冲区从未写出的情况下崩溃，就会造成数据损坏。任何服务器在崩溃恢复之后都可能发生损坏，但在备库从库服务器上发生的可能性显著更高，因为它们执行多得多的 WAL 重放。btree 和 GIN 索引损坏的概率较低。表“可见性映射”损坏的概率要高得多。幸运的是，可见性映射在 9.1 中不是关键数据，因此这种损坏在 9.1 安装中最坏的后果只是清理的瞬时低效。表数据本身不会因此缺陷损坏。

\n

虽然尚无此缺陷导致的索引损坏在实际环境中发生的已知案例，但作为预防措施，建议生产安装在升级到 9.1.6 后的方便时间对所有 btree 和 GIN 索引执行 REINDEX。

\n

此外，如果你打算就地升级到 9.2.X，建议在升级之前在把 vacuum_freeze_table_age 设为零的情况下对所有表执行 VACUUM。这将确保可见性映射中任何残留的错误数据在 9.2.X 依赖它之前被纠正。可以调整 vacuum_cost_delay 来降低清理的性能影响，代价是需要更长时间完成。

There is a low probability of corruption of btree and GIN indexes. There is a much higher probability of corruption of table visibility maps. Fortunately, visibility maps are non-critical data in 9.1, so the worst consequence of such corruption in 9.1 installations is transient inefficiency of vacuuming. Table data proper cannot be corrupted by this bug. While no index corruption due to this bug is known to have occurred in the field, as a precautionary measure it is recommended that production installations REINDEX all btree and GIN indexes at a convenient time after upgrading to 9.1.6. Also, if you intend to do an in-place upgrade to 9.2.X, before doing so it is recommended to perform a VACUUM of all tables while having vacuum_freeze_table_age set to zero.

恢复 9.1 之前的行为：返回 void 的 PL/Perl 函数忽略其最后一条 Perl 语句的结果值；9.1.0 在该语句返回引用时会抛出错误。同时，确保可以为组合类型返回字符串值，只要该字符串符合该类型的输入格式。此外，当函数声明的结果类型不是数组或组合类型时，对分别尝试返回 Perl 数组或哈希的做法抛出错误。（9.1 之前的版本在这种情况下会返回诸如 ARRAY(0x221a9a0) 或 HASH(0x221aa90) 之类毫无用处的字符串。）
