This does not matter because the script is only defining the function
not executing it.  Or are you speaking of an index function or something
like that?  In that case it really behooves you to make the function not
so sensitive to the caller's search path.  There is no way that pg_dump
can know that some function will only work as desired if called with a
particular search_path setting.
