Chris van Eijk: infinite recursion detected in policy: causes and fixes
When PostgreSQL 17 raises 'infinite recursion detected in policy for relation', and what each fix costs on a million rows: from 0.09 ms to 6.6 seconds..

Database Engine & Storage Subsystem Architecture
From an OLTP/OLAP systems architecture, storage tiering, and data durability perspective: - **Zero-Vendor Lock-in Formats:** Leveraging open specifications (e.g. Parquet, Iceberg) ensures multi-engine interoperability without ingestion lock-in. - **Vector & In-Memory Throughput:** Modern memory layouts and SIMD-accelerated execution pipelines minimize latency in real-time retrieval. - **Distributed Resiliency:** Decoupled storage and compute layers enable elastic horizontal scaling with strict ACID guarantees.
Impact on the Open Ecosystem
Empowers data engineers with open, self-hosted alternatives to monopolistic cloud database providers.
