Sure, but you're far too clever not to be able to come up with
something good without any help from me. io_error_return_or_throw()?
store_or_report_io_error()? Or just store_io_error()?

It sounds to me like we're crafting something that is specific to and
can only be used with type input and output functions, so the name
probably should reflect that rather than being something totally
generic like ereturn() or error_stash() or whatever. If we were making
this into a general-purpose way of sticking an error someplace, then a
name like that would make sense and this would be an extension of the
elog.c interface. But what you're proposing is a great deal more
specialized than that.
