SQL-dump with ``GRANT ... WITH GRANT OPTION``

it could be situations when ``pg_dump`` **temporary** changes session authorization.

for example:

```
GRANT SELECT ON TABLE my_sch.my_view TO xxx WITH GRANT OPTION;
SET SESSION AUTHORIZATION xxx;
GRANT SELECT ON TABLE my_sch.my_view TO zzz WITH GRANT OPTION;
RESET SESSION AUTHORIZATION;
```

we should write rule for it, if it possible in current architecture of ``pg-dump-splitter``.
