suggestion for admin "If you are upgrading"

Hi

It might be nice to add a line saying that pgdumpall doesn't do large
objects to section 1.4 of admin, so that when people upgrade from 7.0 to
7.1 they don't accidentally lose their large objects. Perhaps something
like:

pgdumpall doesn't dump large objects by default. If your database uses
large objects, please see section 8.1.4 Caveats.

thanks,
Philip
