   "abstract": "ORCA query optimizer as a PostgreSQL extension",
   "description": "Plugs the Apache Cloudberry / Greenplum ORCA cost-based optimizer into single-node PostgreSQL 18 via planner_hook. ORCA operates on an intermediate XML-based representation (DXL); if it cannot handle a query it falls back to the standard PG planner automatically. Useful for analytical workloads where ORCA's transformation-based search and cost model produce better plans than PG's standard optimizer (TPC-H, TPC-DS, many-relation joins).",
