This setting triggers Extbase to load the related Objects "lazy" (in 
opposition to "eager"). The setting "proxy" addresses a specific variant 
of the Lazy Loading Strategy [1]. This means that the ObjectStorage 
holding the related Objects (like Posts) is replaced by a 
LazyLoadingProxy without the time consuming instanciation of the related 
objects. At the first time the Posts are accessed (e.g. by saying 
getPosts()) the objects are loaded and instanciated.

In the future there may be other loading strategies (like "ghost" for 
1:1 relations).

Jochen
