Using the distributed examples as a guide, I wrote a c++ code to execute a large suite of queries. Each query opens and closes a backend. I notice a *big leak* when large numbers of tuples are returned. I get the same behavior using libpq (with PQclears and PQ finishes explicitly) or using libpq++. I'm probably doing something wrong but I followed the docs and examples carefully. Any ideas or suggestions? Thanks. --Martin ************
