\n此外，Europe/Kiev 时区已重命名为 Europe/Kyiv。另外，以下时区已合并到附近的、人口更多的、自 1970 年以来时钟一致的时区中：Antarctica/Vostok、Asia/Brunei、Asia/Kuala_Lumpur、Atlantic/Reykjavik、Europe/Amsterdam、Europe/Copenhagen、Europe/Luxembourg、Europe/Monaco、Europe/Oslo、Europe/Stockholm、Indian/Christmas、Indian/Cocos、Indian/Kerguelen、Indian/Mahe、Indian/Reunion、Pacific/Chuuk、Pacific/Funafuti、Pacific/Majuro、Pacific/Pohnpei、Pacific/Wake 和 Pacific/Wallis。（这间接影响了已经是这些时区别名的时区：Arctic/Longyearbyen、Atlantic/Jan_Mayen、Iceland、Pacific/Ponape、Pacific/Truk 和 Pacific/Yap。）America/Nipigon、America/Rainy_River、America/Thunder_Bay、Europe/Uzhgorod 和 Europe/Zaporozhye 也被合并到附近的时区中，因为发现它们声称的 1970 年后与这些时区的差异似乎是错误的。在所有这些情况下，之前的时区名称仍作为别名保留；但实际数据是所合并到的时区的数据。
\n这些时区合并导致被合并时区的 1970 年前时区历史丢失，这对于期望 timestamptz 显示一致性的应用程序可能造成困扰。例如，存储的值 1944-06-01 12:00 UTC 在选择 Europe/Stockholm 时区时，之前会显示为 1944-06-01 13:00:00+01，但现在会显示为 1944-06-01 14:00:00+02。
可以使用选项构建时区数据文件来恢复旧的时区数据，但该选择也会插入大量其他旧的（且通常缺乏充分证据的）时区数据，导致相比接受这些上游更改，总变化更多。PostgreSQL 选择按照推荐方式发布 tzdb 数据，据我们所知，大多数主要操作系统发行版也在这样做。但是，如果这些更改给你的应用程序造成了严重问题，一个可能的解决方案是使用 tzdb 的向后兼容选项安装本地构建的时区数据文件（参见其 PACKRATDATA 和 PACKRATLIST 选项）。
