Well, if you stop reading from the file then I don't think more \i's
will matter, no? I'd certainly like to see improvement here, because the
difference in behavior with \i is annoying.
On the bigger question of how to better protect all these cases (cut &
paste, etc), I think the only robust way to do that is for psql to track
intended transaction status itself. With the amount of parsing it's
already doing, maybe that wouldn't be that hard to add. It looks like
this might require extra libpq calls to constantly check in on server
status; I'm a bit surprised that result objects don't include that info.
