Could you build this?
Partial While an API wrapper querying Postgres and generating embeddings is simple, building automated graph construction from relational schemas alongside high-performance hybrid vector-graph indexing requires advanced database systems design.
What it would actually take: A production version requires an automated schema-to-knowledge-graph pipeline (extracting foreign keys and semantic relationships), vector generation, and a graph query engine (like Apache AGE or pgvector integrated with custom graph traversal queries in Postgres). The hard part is efficiently maintaining real-time sync with underlying Postgres change streams (logical replication via WAL) and orchestrating fast hybrid retrieval without introducing severe query latency.
