No. And 8.1 isn't out yet.

Test it first - there might be something different between 7.4 and 8.0
that you're relying on. Read the release notes in 8.0 to find out what
might affect you.
It's generally easier to dump/restore using a version 8 pg_dump - each
version is a bit smarter, and can talk to older servers.
Oh - and make sure you're familiar with the Unicode issues on Windows.
