Yeah, I looked into this when discussing this same concept at PGCon with
folks. There doesn't appear to be a good librsync and, even if there
was, there's a heck of alot of complexity there that we *don't* need.
rsync is a great tool, don't get me wrong, but let's not try to go over
our heads here.
We don't need permissions handling, as an example. I also don't think
we need the binary diff/partial file transfer capability- we already
break relations into 1G chunks (when/if they reach that size), so you
won't necessairly be copying the entire relation if you're just doing
mtime based or per-file-checksum based detection. We don't need device
node handling, we don't need auto-ignoring files, or pattern
exclusion/inclusion, we don't really need a progress bar (though it'd be
nice.. :), etc, etc, etc.
Thanks,
