IIRC, the original discussion had a possible pg_query_cancel(int)
functoin that would cancel a query based on XID or something like that,
and we wanted to differentiate from that. (No such function was ever
created, but it was the reason, IIRC)

Note that at this time there was also a pg_backend_terminate(int) that
would terminate the backend (in fact, IIRC it's still in the code, but
commented out). When both exist, the difference is clear...
