AI Analysis
●●●BangerBig BrainZero to One
Postgres + pgvector + MCP integration solves the AI amnesia problem better than vector DB silos.
Strengths
- •Hybrid semantic and keyword search in a single Postgres instance eliminates vector DB complexity
- •MCP-native integration allows Claude to recall and store memories during any session
- •Knowledge graph baked into the database schema enables relationship tracking between memories
Weaknesses
- •Requires PostgreSQL 16 with pgvector extension, limiting deployment options
- •Knowledge graph visualization needs more sophisticated relationship inference
