We consider pragmas a dead end and not going to extend them further.
However we still need a mechanism for storing session-related things,
like verbosity flags or default engine. We believe, that such settings
are related to the session, not to DB and that is why this patchset
was prepared.
Anyway, thanks a lot for your inputs.
