#pgvector is a PostgreSQL vector extension used directly in these articles.
Definition
pgvector is an open-source extension that adds vector similarity search to PostgreSQL, allowing embeddings to live alongside the rest of your relational data.
Why it matters
It matters when AI retrieval features should stay inside Postgres instead of moving data into a separate vector database before the product actually needs that split.
In this archive
Here pgvector appears in RAG systems, similarity search, embedding storage, hybrid retrieval, and practical decisions about building AI features on top of Postgres. It currently appears across 1 category, mainly AI.
