Anna deleted the OP's answer edited into the question. I put it in an answer for everyone to see. Nathan_scott wrote (slightly edited).

If you are backing up at the time, you may find it more prudent to remove backup_label. Pg_resetxlog is a severe thing.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
