Review Comment:
It seems that GPDB attempted to resolve a critical bug, but it will
encounter issues when transitioning to PG14. To manage this, I’ve implemented a
code fix using macros, so that if we encounter the bug again, we can easily
address it and save ourselves the hassle of troubleshooting in the future.
