Hi,
I haven't read through the thread yet, just tried to apply the patch and run tests.
And it seems that the last attached version is outdated now. It doesn't apply to the master
and after I've tried to fix merge conflict, it segfaults at initdb. 

So, looking forward to a new version for review.

The new status of this patch is: Waiting on Author
