3630: can't happen, because we already elog(ERROR) deep in the
function, which is what I tried to outline above. That's the one
requiring a redesign - because the errors *inside* the function it
calls can certainly happen.
3657: is one of those "should never happen" issues - which we haven't
had any reports of.
3674: see above
3693 is a comment, I assume you mean 3683, which is also one of those
can't happen.

But. I'll look into cleaning those up for HEAD anyway, but due to lack
of reports I think we should skip backpatch. Reasonable?
