RAG & Knowledge Retrieval with PostgreSQL

RAG & Knowledge Retrieval built on PostgreSQL, chosen where it genuinely fits, and swapped where it does not.

Why PostgreSQL for this

Orqent Labs builds RAG systems where accuracy is measured against a labelled question set, so you know the number rather than trusting a vibe.

PostgreSQL is strongest at it handles far more workload than teams expect, with one operational model. For rag & knowledge retrieval that matters because the failure modes of this kind of system tend to cluster exactly there.

The honest trade-off: genuine analytical workloads past a certain scale belong in a warehouse. We say that up front because a stack chosen for fashion rather than fit becomes someone's migration project two years later. We build the smallest thing that proves the case, put it in front of real users, and expand only what earns its keep.

We hand over with runbooks, tests and a team that knows how it works, not a dependency.

We are not a reseller for PostgreSQL and hold no commission on this choice. Where a different option fits your workload better, the recommendation will say so. That is the entire value of asking us.

What is included

  • Ingestion pipeline for your real document formats
  • Chunking and embedding strategy tuned to your corpus
  • Hybrid keyword plus vector retrieval with reranking
  • Citations on every answer, traceable to the source page
  • Permission-aware retrieval that respects existing access rules
  • Retrieval quality benchmarked against a labelled question set

Questions

RAG or fine-tuning?

RAG for knowledge that changes and must be cited; fine-tuning for style, format and task behaviour. Most production systems use RAG for the facts and light fine-tuning or few-shot prompting for the form.

How accurate will it be?

We build a labelled question set from your domain and report retrieval precision and answer accuracy against it. That number is the deliverable. We do not ship a system whose quality nobody has measured.

Can it respect our existing permissions?

Yes. Retrieval is filtered by the user's actual entitlements, so the assistant can never surface a document the user could not already open.

Alternatives for rag & knowledge retrieval

Same capability, different stack. Each page states its own trade-off.
