Comment:

 Here's an interesting case for you guys to play with:

  POLYGON((10 10,10 20,30 20,30 10,20 10,20 30,30 30,30 20,5 20,5 25,10 25,
 10 10))

 If the goal of a ST_CleanGeometry is to maintain as much information from
 the input
 but make it into a valid shape, the above would sound to me as becoming a
 mix
 of two polygons and two lines.
