pg_grpc is a PostgreSQL extension that allows making gRPC calls directly from SQL queries, using runtime server reflection to resolve protobuf schemas without requiring .proto files or code generation. It's interesting because it bridges the gap between relational databases and modern RPC services, enabling data enrichment or external service calls within database transactions.

Target audience: backend devs, data engineers
