pg_dump scans dumped objects and rename them by rules, that could be set by 
pg_dump argument line options.
As I now, pg_dump and pg_restore use the same functions, so, renaming mechanism 
can be integrated in pg_restore too.
pg_restore will scan dumped objects and rename them by rules.

In future, rules could be applied on all database objects.
