Call gRPC services
directly from SQL

pg_grpc is a PostgreSQL extension that lets you invoke unary gRPC methods from inside a SQL query - no sidecar, no codegen, no application layer in the middle.

Get started
psql - postgres@db:5432
pg_grpc=# SELECT grpc_call(
pg_grpc-#     host    => 'api.internal:9090',
pg_grpc-#     method  => 'users.UserService/GetUser',
pg_grpc-#     payload => '{"user_id": 42}'::jsonb
pg_grpc-# );

              grpc_call
