Is it possible to have a FATAL error that crashes a backend and for it
to *not* have written an abort WAL record for any previously active
transaction?
I think yes, but haven't managed to create this situation while testing
for it. If we either *always* write a WAL record, or PANIC then that
makes some coding easier, so seems sensible to check.
