Transiently setting session_authorization in a function SET clause had a similar effect. A related bug was that if a parallel worker inspected current_setting('role'), it saw none even when it should see something else. The PostgreSQL Project thanks Tom Lane for reporting this problem.

修复方法是对现在独立的表的每个有问题的约束执行 ALTER TABLE DROP CONSTRAINT，然后重新添加该约束。如果重新添加约束失败，说明已经有错误数据混入。需要手动恢复引用表和被引用表之间的一致性，然后重新添加约束。
以下查询可用于识别损坏的约束，并构造重建它们所需的命令：

修复 EXPLAIN 中的 “failed to find plan for subquery/CTE” 错误（Richard Guo，Tom Lane）§ §
当试图打印子查询的 RECORD 类型输出的字段引用，而该子查询已从执行计划中完全优化掉时（至少在具有常量为假的 WHERE 条件时可能发生），就会出现这种情况。执行计划中不再有任何内容可以标识原始字段名，因此回退到对第 N 个记录列打印 f。（如果记录输出来自 NROW() 构造器，这实际上也是正确的做法。）

生成列已经有一个指定列内容的表达式，因此包含 USING 没有意义。

\n此 tzdata 版本将旧的 System-V 兼容性区域名称更改为与对应地理区域重复；例如 PST8PDT 现在是 America/Los_Angeles 的别名。主要可见后果是，对于标准化时区引入之前的时间戳，该区域被认为代表命名位置的本地平均太阳时。例如，在 PST8PDT 中，timestamptz 输入如 1801-01-01 00:00 之前会被渲染为 1801-01-01 00:00:00-08，但现在会被渲染为 1801-01-01 00:00:00-07:52:58。
另外，包含墨西哥、蒙古和葡萄牙的历史修正。值得注意的是，Asia/Choibalsan 现在是 Asia/Ulaanbaatar 的别名而非独立区域，主要是因为这些区域之间的差异被发现是基于不可靠的数据。
