Tracing execution of stored functions. See Tracker CORE-4345 (V. Khorsun).

Trace no longer ignores the fact that users from different security databases are actually different users. It now “knows” in which security database a particular SYSDBA was authenticated or where a privileged user's elevated privileges are established. It is no longer possible, for example, for a user named SYSDBA to access security3.fdb if it is not currently authenticated for that access. See See Tracker CORE-4851 (A. Peshkov).
