Sure, C-c just sends a SIGINT. But IIRC the problem wasn't so much cancelling running queries, SIGINT appears to work fine there, it's that a connection blocked on waiting for client input doesn't wake up when sent a signal. To fix that you'd need to change the signal mode and teach the various input layers (like SSL) to handle the EINTR case.
