Consider a scenario like:
User A starts transaction.
User A issues a LOCK TABLE (or does something to lock it)
User A goes on vacation without commit/rollback
User A might well be Program A instead, of course. Caught in a tight
loop, waiting for user input, or whatever.
In this case, SIGINT (query cancel) will not help, because all locks
held by the transaction will still be held.
If there was a way to "force rollback" a connection, that could be done.
Buf AFAIK there are none? And would those be safer/better than
terminating the backend?
