Secure SETSESSIONUSER Privilege

The SETSESSIONUSER privilege allows one user to switch the session authorization ID of the connection to another user. This allows one user to run SQL statements as another user. It is recommended that Trusted Context be used as a stronger assertion of user identity where such a feature is required.
