I need testers for incremental backups (similar Oracle)

Hello all.
I'm working on incremental backup based on tracking of memory pages
(ptrack).
Now project in beta stage. And I did not have many feedbacks for catch
bugs.

I think it is important project for postgres exploitation. This approach
can really speed up incremental backup with small overhead.
This project append patch to postgres core and add new features to
pg_arman.

Small HOWTO and all links I place here:
https://gist.github.com/stalkerg/dda6fed9ca4bd7cc424ad439bac04303

I will be answered here and at github.

Thanks!
