Dear Cloudberry Community, I hope this email finds you well. I would like to propose upgrading the Cloudberry core from PostgreSQL 16 to version 18. The primary goal of this upgrade is to closely align Cloudberry with the upstream development lifecycle. By keeping our core in sync, we will not only strengthen our ties with the PostgreSQL ecosystem but also streamline the workflow for Cloudberry developers to contribute code back to the PostgreSQL community. As you may know, PostgreSQL 17 and 18 introduce numerous groundbreaking performance features, including:
- Asynchronous I/O - Parallel log processing These enhancements hold immense value and represent milestone improvements for Cloudberry's capabilities. Furthermore, following a detailed preliminary investigation and research phase, I am confident that we can accomplish this kernel upgrade within a much shorter timeframe than initially anticipated. I would love to gather your thoughts on this proposal. Looking forward to your feedback. Best regards, Jinbao Chen
