   "description": "storage_engine v2.4 improves real TPC-H planning for colcompress with narrow planner-hook fixes for Q7, Q18, Q20, and Q21 plus nested-loop avoidance for post-join aggregate shapes such as Q9 on PG16+. rowcompress index lookups now expose reliable scan/cache counters through engine.rowcompress_scan_stats() and reuse backend-local metadata plus decompressed batches safely across repeated probes. colcompress keeps its page cache alive across rereads in the same backend, improving repeated-scan latency without query rewrites. The extension is validated on PostgreSQL 15–19 (PG15: 294 tests; PG16–PG18: 293 tests each; PG19: 297 tests). All catalog objects live in the engine schema; C symbols use the se_ prefix.",
