The deciding difference is operational: Postgres (rolled by hand) can run on infrastructure you control, Supermemory cannot. If that constraint is real for you, it settles the choice before anything else is considered.
Memory graph plus automatic user profiles, with connectors that sync from Drive, Gmail, Notion and GitHub.
Closest thing here to memory and RAG in one product: the graph tracks contradictions and recency, and the connectors mean you are not writing an ingestion pipeline first.
A messages table and a summaries table. Boring, auditable, yours.
Start here. Move to a memory product when you can name the query it makes fast.
