Assuming you have set recovery_user and recovery_passwd correctly, I'm
not sure what's going on. IMO, the error message is very rare. It's so
rare and there's a bug in the error path, which had not been found for
long time. Can please try attached patch? The patch add a little bit
usefull info to the error message above.
