Hi all, I would like to share a new update on our ongoing PostgreSQL kernel upgrade effort for Apache Cloudberry. Over the past 2 months, we have made steady progress and successfully completed several key phases of the integration. Here is the latest status: ~> Merge New Kernel into Work Branch (Done) ~> Resolve Conflicts (Done) ~> Fix Compile Errors (Done) ~> Init Database (Done) ~> Start the cluster (Done) ~> Pass the Postgres parallel schedule tests (Done) ～> Pass the Cloudberry schedule tests (Will start) At this stage, most of the core enablement work for PostgreSQL 16.9 has been completed. Next, we will start to try to pass the Cloudberry schedule tests. You can track our latest progress here: - Work Branch: https://github.com/apache/cloudberry/tree/cbdb-postgres-merge - GitHub Project: https://github.com/orgs/apache/projects/497 Hope we can achive the milestone earlier! Thanks again!
