On the other hand, if we make the change visible because of a
compilation failures, then modules would become aware of the problem and
react?  I would not expect modules to set missing_ok to true anyway as
they expect those objects to exist, so I can live with a new function.
What about naming those GetForeignServerExtended and
GetForeignDataWrapperExtended?
