Archive version 1.12 means that the file was emitted by a 9.0 or later
version of pg_dump. So you'll need a 9.0 or later version of pg_restore
to read it. Depending on what server version it was dumped from, you
might have some problems restoring the objects in the dump into an 8.4
server, too.
BTW, if you really are running 8.4.0, you would be well advised to
update to a newer minor release. The 8.4 release series is currently at
8.4.11, meaning you're missing 11 minor versions worth of bug fixes,
some of which were pretty critical.
