        Some applications might rely on the old text-based behavior of
-       run-time lookup of the sequence name. This can still be done by
+       run-time lookup for sequence names. This can still be done by
        casting the argument to <type>text</>, for example
        <literal>nextval('myseq'::text)</>.

        Pre-8.1 schemas loaded into 8.1 will use the previous, text-based
-       representation and therefore will not have these protections.
