Maybe. The mention of elog.c in the same breath with critical
sections is already enough to scare me; we surely daren't invoke
gettext() in a critical section, for instance. I feel the most
we could hope for here is to report a constant string that would
not get translated till later, outside the critical section.
That seems less about infrastructure and more about how the AIO
error handling/reporting code is laid out. In the meantime,
if leaving the error out of this view is enough to make the problem
go away, let's do that.
