I do not know how to do that. I learned that I can send a SIGINT to a
backend to cancel a query, but I dont know how to kill just one transaction.
I have only "pg_getpid" and "pg_killpid" as interfaces to system functions
"getpid" and "kill".
BTW, what information can I get about the current running backends on the
internal structures? Or do I have to ask the OS?
Thank you,
