The premise
AI can scaffold an AI pgvector RAG pipeline with schema, index, ingestion job, and query helpers.
What AI does well here
- Generate a schema with content, embedding, and metadata columns
- Draft index DDL for HNSW or IVFFlat with sane starting parameters
What AI cannot do
- Pick recall-versus-latency settings without measurement on your corpus
- Decide PII handling at the database layer
