Postgres as Your Vector Database: When and Why

pgvector inside the Postgres you already operate covers 90% of RAG workloads at a fraction of the cost - with joins, transactions, backups and existing operational muscle.

Why it matters

The cases where you outgrow pgvector are real but narrow: massive single-corpus QPS, complex multi-tenant filtering at huge scale, ultra-low-latency edge.

How Bhogar AI approaches it

Bhogar AI defaults to pgvector for new KBs and lets you migrate to Pinecone, Weaviate or Qdrant when telemetry says you should - not before.

• pgvector default with HNSW
• Joins, transactions and backups for free
• Migration paths to managed vector DBs
• Per-KB cost telemetry
• When-to-migrate criteria documented

What you get

Customers save substantial vector-DB spend without giving up retrieval quality or operational simplicity.
