This is surprising!
Last year, we launched one project named Cloudberry Database. It's one derivative of Greenplum Database, and is compatible with Greenplum Database. Cloudberry Database is shipped with a newer PostgreSQL 14.4 kernel (scheduled kernel upgrade yearly) and a bunch of features Greenplum Database lacks or does not support.
If you're using open source Greenplum Database, welcome to choose the Cloudberry Database as the alternative.
