pgvector + Voyage for AI companion memory — 5× less RAM than Mem0
A walkthrough of how we run AI companion memory inside Postgres with pgvector + Voyage embeddings, and why dropping the Mem0 sidecar shrank our engine's resident memory by roughly 5×. Concrete schema, the embed-write-search loop in Rust, and the deployment math behind self-hosting on a shared-cpu-1x machine.
