I was able to build successfully using Meson on PostgreSQL 16. However, when attempting the same on the latest master(with the revived changes), I encountered a few errors. We are currently investigating these issues and working on the necessary fixes.

I’ll keep you updated once the Meson-related fixes are ready.

Thank you for the suggestion.

Splitting the patch into smaller, constituent pieces makes sense and would certainly help with clarity and review.

Appreciate your guidance.
