Explore with Alex OS

Alex uses PostgreSQL with the pgvector extension to store and query embeddings in Alex OS, the retrieval layer behind this site.

PostgreSQL

A relational database used here specifically for vector embedding storage via the pgvector extension. Active in production as the optional embeddings store for Alex OS.

How it's used

Serves as the backing store for Alex OS's embedding index — enabling semantic search and retrieval-augmented generation (RAG) queries against Alex's content. See the Alex OS project for context on how this fits into the broader retrieval pipeline.

Skill level

Working knowledge, grounded in practical use on a real project (Alex OS). Not a database administration role — the focus is on pgvector integration for RAG and knowledge retrieval workflows.
