You should run valgrind with --leak-check=full to see details. I tried your program and I get "still reachable" only when SSL is enabled; all the memory is in OpenSSL. Dou you use SSL? Without SSL (sslmode=disable) I get no "still reachable" memory. I don't know of reachable memory is a problem, I'd suspect not.
