Why Postgres is often a better choice than dedicated Vector Databases in 2026 The Definitive Guide to High-Dimensional Data Architecture In 2026, we've reached a point where traditional SQL indexing fails to capture the semantic nuance required for modern RAG pipelines. While relational tables are far from dead, the 'Complexity Tax' of forcing unstructured data into structured schemas is becoming too high. This post explores why we are shifting towards Vector-native architectures for AI memory . 1. The Geometry of Data: What is an Embedding?
