当分区表有一个不与约束关联的索引，但某个分区有一个等效的索引且该索引与约束关联时，分离该分区会出现异常行为，导致前分区的约束具有不正确的 coninhcount 值。这会在后续对该约束进行任何操作时引发问题。

执行器假定在对分区表的查询规划和执行之间不会有分区被分离。自从引入 DETACH PARTITION 的 CONCURRENTLY 选项后，这一假设不再成立，使得在使用该选项时查询执行可能会出现短暂的失败。
在最后一个子分区被删除后，正确地将分区表的 pg_class.reltuples 字段更新为零（Noah Misch）§

检测计算新数组维度时的另一个整数溢出情况（Joseph Koshakow）§
\n拒绝将数组维度 [-2147483648:2147483647] 应用于空数组。这与 CVE-2023-5869 密切相关，但看起来是无害的，因为数组最终仍然为空。
检测在对目录缓存条目的字段进行解压缩时该条目变为过期的另一种情况（Noah Misch）§
\n在展开目录元组的行外字段时发生的原地更新可能会被遗漏，导致目录缓存条目缺少原地更改但不被认为是过时的。这仅在 pg_database 目录中可能发生，因此影响范围较窄，但可能会导致异常行为。
正确检查由 INSERT ... DEFAULT 目标的视图列的可更新性（Tom Lane）§
如果这样的列不可更新，我们应该报告相应的错误。但该检查被遗漏了，随后的代码会报告一个不太有用的错误，如 “attribute number N not found in view targetlist”。
避免对不正确的递归查询报告无用的内部错误（Tom Lane）§
\n重新排列错误检查的顺序，以便在 WITH RECURSIVE 查询在 UNION 的第二个分支中没有自引用，但在其他位置（如 ORDER BY）有自引用时，抛出针对性的错误。
当排队的 AFTER 触发器不再存在时不抛出错误（Tom Lane）§
事务可能会执行一个操作将延迟的 AFTER 触发器排队等待后续执行，然后在触发器执行之前将其删除。之前这会导致诸如 “could not find trigger NNNN” 之类的奇怪错误。如果触发器在应该执行的时间点已不存在，静默地不做任何操作似乎更好。
