\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 contrib/intarray 的 GiST 操作符类在空数组使用 <@ 时不失败的问题（Tom Lane）
像 array_column <@ constant_array
唯一实际可向后移植的修复要求 <@ 索引搜索扫描整个索引，本补丁就是这么做的。这很不幸：这意味着查询性能可能比 plain 顺序扫描更差。
性能受此更改不利影响的应用有两种选择。可以改用没有此 bug 的 GIN 索引，或者把 array_column <@ constant_arrayarray_column <@ constant_array AND array_column && constant_array
允许 configure --with-python 在只能找到 python3 或只能找到 python2 时成功（Peter Eisentraut、Tom Lane）
先搜索 python，再搜索 python3，再搜索 python2，使 configure 在没有名为 python 的可执行文件这一日益常见的情况下也能成功。仍然可以通过设置 PYTHON 环境变量覆盖这一选择。
