-       When an expression like <literal>nextval('myseq')</> appears in a
-       column <command>DEFAULT</> expression or view, the referenced
-       sequence (here <literal>myseq</>) is now looked up immediately,
-       and its pg_class OID is placed in the stored expression. This
-       representation will survive renaming of the referenced sequence,
-       as well as changes in schema search paths. The system also
-       understands that the sequence reference represents a dependency,
-       so the sequence cannot be dropped without dropping the
-       referencing object. Previous releases stored this information as
-       a simple text string, with none of the benefits outlined above.

        <literal>nextval('myseq'::text)</>.
