> The current LanguageConnectionContext keeps the user authorization identifier for an SQL session.
> The lcc is shared context also for nested connections (opened from stored procedures).
> So far, for roles, the current role has been stored in the lcc also. However, SQL requires that
> authorization identifers be pushed on a "authorization stack" when calling a stored procedure, cf.
> SQL 2003, vol 2, section 4.34.1.1. 
> This allows a caller to keep its current role after a call even if changed by the stored procedure.
> This issue will implement the current role name part ("cell") of the authorization stack.
