+ This event is called with the DBAPI exception instance
+ received from the DBAPI itself, *before* SQLAlchemy wraps the
+ exception with it's own exception wrappers, and before any
+ other operations are performed on the DBAPI cursor; the
+ existing transaction remains in effect as well as any state
+ The use case here is to inject low-level exception handling
+ into an :class:`.Engine`, typically for logging and
+ debugging purposes. In general, user code should **not** modify
+ any state or throw any exceptions here as this will
+ interfere with SQLAlchemy's cleanup and error handling
+ Subsequent to this hook, SQLAlchemy may attempt any
+ number of operations on the connection/cursor, including
+ closing the cursor, rolling back of the transaction in the
+ case of connectionless execution, and disposing of the entire
+ connection pool if a "disconnect" was detected. The
+ exception is then wrapped in a SQLAlchemy DBAPI exception
