Slony for windows is available but Iam not sure how well the replication between windows and Linux will go, I haven’t tried (on my list of to do for ages). Based on the theory, it should work because you will use connectivity details to connect
two nodes and there is no dependency on the architecture of the host.
There are links to developer.pgadmin.org in the installation chapter of slony manuals, which has a sample screen shot of GUI installation for windows, although I could only see references to win32.
Another triggers based replication tool is SymmetricDS, again windows to Linux needs to be tested.

You can use the pg_dump from the linux-box to take the dump using directory-format and multiple processes, and also multiple processes for the restore.
You can also try to use a trigger-based replication (londiste, slony) to build a replication from 9.0 to 10, but i'm not sure if those tools are available under windows.
