Score: 6.5/10 (Innovation: 5, Technical: 8, Documentation: 7, Utility: 6)

pgnudge is a lightweight async Python library that uses PostgreSQL's replication protocol to notify applications of table changes without row data or server-side objects, enabling efficient cache or read model invalidation. Its innovative zero-footprint approach with temporary slots and no database driver makes it uniquely easy to adopt while maintaining correctness.
