1. v8.2.0 is a mistake, make sure you are running the latest stable
patch rev. v8.2.5.
2. You will need to dump and reload, use the v8.2.5 pg_dump to connect
to the v7.4.13 databases and restore.
3. There are specific behavior differences. The one that comes to mind
most prominently is that float/double can no longer be ''.
4. Read the release notes from the docs
5. 8.2 is a completely different beast in terms of performance and
configuration.

Joshua D. Drake
