Mayur B.: PGConf.EU 2026: Into the PostgreSQL Multiverse
Somewhere in the multiverse, there is a version of you who attends every interesting talk at PGConf.EU.
Executive Summary
Somewhere in the multiverse, there is a version of you who attends every interesting talk at PGConf.EU. Unfortunately, in this universe, PostgreSQL has parallel query execution. Last year, I created an Underground Map for Database Nerds to navigate PGConf.EU without getting lost in the schedule. This year, the conference returns to Valencia, October 20–23, with five parallel tracks and the same old problem: too many good talks occupying the same space-time coordinates.
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.
