Hello, Magnus, Peter!

I'm excited that this feature emerged, thanks for the patch. Hope it will help 
to fix some mistakes made during initdb long time ago...

Peter, can I ask for some pointers in searching for previous versions?
I want to review patch this patch and some code comparision could be handy....

So far I've found only this [0,1] (without code) and threads mentioned by 
Magnus [2,3]

Or do you mean extracting "worker+lancher" for reuse for other purposes?

Best regards, Andrey Borodin.
