This is advisable for major revisions, like from 7.4 to 8.0 or 8.0 to 8.1. My problem (which was already covered on the postgresql-general list) is that I have a database containing non-UNICODE characters which restored just fine up until now, but the new UNICODE checks in the minor revision 8.0.8 refuses to restore my databases because of mentioned characters.

Thanks for that. That is exactly what I needed to know.
