Relationship with the OpenClaw Ecosystem

PostgreSQL is an optional database backend for OpenClaw. For enterprise-level deployments requiring more robust data management capabilities, OpenClaw supports using PostgreSQL as an alternative to SQLite for data storage. PostgreSQL's advanced features (such as JSON support, full-text search, pgvector vector search) provide OpenClaw with enhanced data processing and AI search capabilities, making it suitable for multi-user and large-scale deployment scenarios.
