Just use pg_restore -t tablename (and the other options according to
your pg_dump) and write the results in a file. Use an editor to change
tablename to your new tablename in the result. If you are absolute
sure your tablename does not appear as data payload in the table,
you can use sed like this:
pg_restore -t tablename | sed -e "s/tablename/newtablename/" | psql
