When to use
Optimised for: relationship modeling + reasoning + governance over pure vector
Anti-fit: not for purely-vector or simple-RAG use cases (graph adds setup cost)
Pros & cons
Pros
Postgres extension that adds OpenCypher graph queries — KG without leaving Postgres.
Cons
Performance plateaus at large graph sizes; ecosystem of integrations smaller than Neo4j.
