> This method is the only leak of H2 internals to the outer code. Close analysis of code
reveals that the only reason we have it is *JDBC metadata*. Need to create a method which
will prepare metadata for a statement and return it as a detached object. Most probably we
already  have all necessary mechanics. This is more about refactoring.
