Comment (by pramsey):

 MULTIPOLYGON is allowed to touch at one point:
 {{{
 select isvalid('MULTIPOLYGON(((0 0, 0 1, 1 1, 1 0, 0 0)), ((1 1, 1 2, 2 2,
 2 1, 1 1)))');
  isvalid
 ---------
  t
 (1 row)
 }}}
 Gets more complex as the rings start to share whole segments... in those
 cases the boundaries should actually be dissolved... which is what the
 buffer(0) case does.
