Comment (by pramsey):

 So much yearning for this change! Can I suggest a quick document that
 lists all the relevant functions and their current and desired behaviour,
 because it seems like there's a lot of interlocking stuff necessary to
 make a consistent fix. In addition to ST_GeometryN and ST_NumGeometries,
 also ST_Dump needs to be harmonious. Are there others?
