如果表还有至少两个大于 min_parallel_index_scan_size 阈值的索引，则并行 VACUUM 会无法处理低于该阈值的索引。这可能导致那些索引变得损坏，因为它们仍然包含对已被 VACUUM 移除的堆条目的引用；使用此类索引的后续查询可能会返回不应返回的行。此问题不影响 autovacuum，因为它不使用并行清理。但是，建议对具有合适索引大小组合的手动执行清理的表重建索引。
修复 CREATE INDEX CONCURRENTLY 以等待最新的预备事务（Andrey Borodin）§
刚刚预备的事务插入的行可能会从新索引中遗漏，导致依赖该索引的查询错过此类行。之前对此类问题的修复未能考虑到在 CREATE INDEX CONCURRENTLY 检查时仍在进行中的 PREPARE TRANSACTION 命令。与之前一样，在启用了预备事务（max_prepared_transactions > 0）的安装中，建议重建所有并发构建的索引，以防在构建时发生了此问题。
避免竞态条件导致后端无法将新行的条目添加到正在并发构建的索引中（Noah Misch，Andrey Borodin）§
\n虽然此情况在实际环境中似乎很少发生，但它可能影响使用 CONCURRENTLY 选项构建或重建的任何索引。建议重建此类索引以确保其正确性。
修复 REINDEX CONCURRENTLY 以保留附加到目标索引上的操作符类参数（Michael Paquier）§
修复克隆包含非内置对象的数据库时共享依赖关系的错误创建（Aleksander Alekseev）§
\n此错误在实际中的影响可能是有限的。原则上，它可能允许在角色仍拥有对象时被删除；但大多数安装永远不会想要删除曾被用于向 template1 添加对象的角色。
