------------------------------------------------------------------
Added 01.patch:
- DB is considered empty if have no tables/views and functions.
- If DB exist and is empty, then REPL LOAD will just alter the lastReplID part
of DB parameters using DDLTask for alter DB.
- There is no way to set the description for the DB in case of empty DB.
- If DB exists and is not empty, then REPL LOAD continues to throw exception.
Request [~sushanth], [~thejas] to review the patch.

> This is a potential usecase where a user may want to manually create a db on
> destination to make sure it goes to a certain dir root, or they may have
> cases where the db (default, for instance) was automatically created. We
> should still allow replicating into this without failing if the db is empty.
