+      This is more of a safety precaution, since normally no objects
+      should be dropped while the database is being cleaned, but in
+      the event that a change in the code to remove other objects is
+      made, these drops should still not be logged.
+
+      Notice that the binary log have to be enabled over the call to

+      as disabled and will not log the drop database statement on any
