> Since we've implemented a transactional SQL, we need to reflect it in our JDBC driver.
At the moment our implementation of {{java.sql.DatabaseMetaData}} returns incorrect data.
For example, methods
>  * {{boolean supportsTransactions()}}
> and 
>  * {{boolean supportsTransactionIsolationLevel(int level)}}
> return hardcoded {{false}} value, which is incorrect if MVCC is enabled. We need to
fix it.
