It's not necessary for adding a new table, index, view or function.  You just 
need to make sure you create them on all nodes where they will be used.

You must use it to add a new field to an existing table and to add triggers to 
existing replicated tables.

Check out the documentation here:

Especially the section:
15.1. Changes that you might not want to process using EXECUTE SCRIPT
