my-ship-it opened a new pull request, #1674:
URL: https://github.com/apache/cloudberry/pull/1674

   ## Summary
   
   Cherry-picked upstream PostgreSQL tzdata updates from 2022f through 2025b, 
bringing the bundled timezone data from 2022a to the latest version.
   
   This fixes the `America/Mexico_City` timezone issue where the database 
incorrectly applies DST (CDT/UTC-5) after Mexico abolished Daylight Saving Time 
in October 2022.
   
   Other notable changes include DST law changes for Greenland and Chile, new 
timezones (`America/Ciudad_Juarez`, `America/Coyhaique`), and historical 
corrections for multiple regions.
   
   Fixes https://github.com/apache/cloudberry/issues/1670
