Rather incorrect text in admin guide

In the admin guide, under the section "Large Databases" is the
following paragraph:

    Since Postgres allows tables larger than the maximum file size
    on your system, it can be problematic to dump the table to a
    file, since the resulting file will likely be larger than the
    maximum size allowed by your system. As pg_dump writes to the
    standard output, you can just use standard *nix tools to work
    around this possible problem.

This is a generalization of, most likely, a failing in linux.

NetBSD (which I use) will allow file sizes up to 2^64 -- I don't think
anyone has generated a postgresql database that large yet.

You might want to qualify that with "Operating systems which support
64-bit file sizes (such as NetBSD) will have no problem with large
databases" or "some operating systems are limited to 2-gigabyte files
(such as linux)"
