Eisentraut: The reverts will continue until morale improves
PostgreSQL core team member Peter Eisentraut has written a blog post reflecting on the " unusually high number of features " that have been taken out of the upcoming PostgreSQL 19 release since the beta period began.
Executive Summary
PostgreSQL core team member Peter Eisentraut has written a blog post reflecting on the " unusually high number of features " that have been taken out of the upcoming PostgreSQL 19 release since the beta period began. Some of the reverted features had significant architectural defects that would have been hard to fix quickly and during beta. But there was also a long tail of relatively harmless issues involving various edge cases.
Artificial Intelligence Architecture & Model Evaluation
From an artificial intelligence architecture, model weights governance, and inference efficiency perspective: - **Weights Accessibility & Sovereignty:** Evaluates whether weights are open for private self-hosting or locked behind centralized cloud APIs. - **Quantization & Edge Performance:** Kernel optimizations (4-bit/8-bit GGUF, AWQ, EXL2) allow high tokens-per-second on consumer GPUs and Apple Silicon. - **Reasoning & Architectural Scaling:** Scrutinizes mixture-of-experts (MoE), attention mechanisms, and fine-tuning datasets against open community benchmarks.
Impact on the Open Ecosystem
Protects developers and enterprises from proprietary black-box entrapment, fostering auditable, sovereign AI infrastructure.
