... Ouch, I was too short-sighted :( That is pretty natural to do
so after hearing that. I should have pointed this at the previous
discusion.

I assume the primary usage of this patch to be, as described
before, Dissolving a recovery freezing caused by wrongly placed
backup label. Crash recovery has been already done at that time
so resetxlog's current behavior seems also fittin the situation,
I suppose.

Ok, I'm doing modify it to reset backup locations by default and
remove the new option '-b' to do that. Since this seems looking
to be a bug for the poeple, I'll provide backpatches back
to... 8.4? (Final release of 8.4 is scheduled at July 2014)

Concerning documentation, I see no need to edit it if no one
wants it more detailed after the visible option has been called
off.

regards,
