刚刚预备的事务所插入的行可能被遗漏在新索引之外，导致依赖该索引的查询漏掉这些行。此前针对此类问题的修复没有考虑到在\n CREATE INDEX CONCURRENTLY 检查时尚在执行中的\n PREPARE TRANSACTION 命令。与之前一样，在启用了预备事务的安装（max_prepared_transactions > 0）中，如果并发构建索引时可能发生过此问题，建议对这些索引执行 REINDEX。\n
避免可能导致后端进程无法把新行的条目加入正在并发构建的索引的竞态条件（Noah Misch、Andrey Borodin）\n
虽然这种情况在实际中显然很少见，但它有可能影响任何使用\n CONCURRENTLY 选项构建或重建的索引。建议对所有这类索引执行 REINDEX 以确保其正确。\n
修复 float4 和 float8 的哈希函数，使其对 NaN 产生一致的结果（Tom Lane）\n
由于 PostgreSQL 的浮点类型认为所有 NaN\n 彼此相等，哈希函数就必须对 IEEE 754 标准中所有表示 NaN 的位模式产生相同的哈希码。此前这一点没有做到，这意味着哈希索引和基于哈希的查询计划可能对非规范 NaN 值产生错误结果。（'-NaN'::float8 是在大多数机器上产生这种值的一种方式。）如果浮点列的哈希索引有可能包含这种值，建议对其执行\n REINDEX。\n
防止 wal_level = minimal 时\n CREATE TABLESPACE 崩溃恢复期间的数据丢失（Noah Misch）\n
如果服务器在 CREATE TABLESPACE 与下一个检查点之间崩溃，重放会完全移除新表空间目录的内容，并依赖后续的 WAL 重放来恢复该目录中的一切。这与跳过写 WAL 的优化（例如向刚创建的表执行\n COPY）配合不佳。这类优化只在\n wal_level 为 minimal 时应用，而 v10 及之后版本中这不再是默认值。\n
不要丢弃目标为未指定类型修饰符的同一类型的转换（Tom Lane）\n
例如，如果列 f1 的类型是\n numeric(18,3)，分析器过去会以它不会产生运行时效果为由，直接丢弃 f1::numeric 这样的强制转换。这没错，但表达式呈现出的类型仍应被视为普通\n numeric，而不是 numeric(18,3)。这对于正确解析更大的构造（例如递归 UNION）的类型很重要。\n

允许在 PL/pgSQL 例程最外层块中使用 EXIT（Tom Lane）\n

移除 pg_ctl 对所生成命令总长度的硬编码限制（Phil Krylov）\n
例如，这解除了能传递给 postmaster 的命令行选项数量的限制。pg_ctl 处理的单个路径名（如 postmaster\n 可执行文件名或数据目录名）在大多数情况下仍限于\n MAXPGPATH 字节。\n
修复 pg_dump 正确转储非全局默认权限的问题（Neil Chen、Masahiko Sawada）\n
如果一条全局（无限制的）ALTER DEFAULT PRIVILEGES\n 命令撤销了某个默认存在的权限（例如函数的 EXECUTE），随后一条受限的 ALTER DEFAULT PRIVILEGES 命令又为选定的角色或模式重新授予了该权限，pg_dump\n 未能正确转储这条受限的权限授予。\n
