My reasons for not liking the current GUC name are hinted at above. I think
we'll want a version of this that just fails the transaction once we
have the infrastructure. So we should choose a name that allows for
a complimentary GUC.

but I don't like that much. Not sure what'd be good, the best I
currently can come up with is:
idle_in_transaction_termination_timeout =
idle_in_transaction_cancellation_timeout =
