Backup using GiT?

I have recently had to teach myself how to use git and the thought came to me
that this tool might provide a fairly low setup cost way of passing pg_dumps
over the network to our off site data store. Think Rsync, but on a file
content basis; just the content diff gets transmitted.

GiT works by compressing deltas of the contents of successive versions of file
systems under repository control. It treats binary objects as just another
object under control. The question is, are successive (compressed) dumps of
an altered database sufficiently similar to make the deltas small enough to
warrant this approach?

Comments? (not my my sanity, please)
