Surely this para can be removed?

<para>
If you are using tablespaces and migrating to 8.4 or earlier, there must
- be sufficient directory permissions to allow pg_upgrade to rename each
+ be sufficient directory permissions to allow <application>pg_upgrade</> to rename each
tablespace directory to add a ".old" suffix.
</para>

There are some limitations when migrating from 8.3 to 8.4, but not when
migrating from 8.3 to 9.0, because we added a feature to 9.0. Can you
give a specific example?

Well, I didn't say "every".

Uh, the heading above that item is:

<title>Limitations in migrating <emphasis>from</> PostgreSQL
8.3</title>

What is unclear there? It covers going to 8.4 and 9.0.
