+ Because <application>pg_dump</application> is used to tranfer data
+ to newer versions of <productname>PostgreSQL</>, the output of
+ <application>pg_dump</application> can be loaded into
+ newer versions of <productname>PostgreSQL</>. It also can read older
+ <productname>PostgreSQL</> databases. However, it usually cannot
+ read newer <productname>PostgreSQL</> databases or produce dump output
+ that can be loaded into older database versions. To do this, manual
+ editing of the dump file might be required.
