I agree I find the boost documentation... sparse,  
http://www.boost.org/doc/libs/1_48_0/libs/ptr_container/doc/ptr_container.html 
e.g. states a couple of lines down in the Motivation section
  "for each of the standard containers there is a pointer container 
equivalent that takes ownership of the objects in an exception safe manner"

Still that wasn't clear enough for me so I wrote a small test program 
and tested it. ( I didn't even find a description of what clear() does 
e.g. that it removes and deletes the elements )
