Comment(by dustymugs):

 So, are you two proposing the elimination of the following wrapper
 functions:

 ST_Count
 ST_Sum
 ST_Mean
 ST_Stddev
 ST_MinMax

 and the Approx versions of the above?  I'm just confirming as my vote is
 "yes" to eliminating them!  Granted, this would eliminate the shortcut
 that Pierre mentioned earlier this week and I implemented for ST_Count.

 On a side note, I really don't like the fact the inefficiency of getting a
 raster's width and height using ST_Width and ST_Height.  As I was writing
 the ST_Histogram function for coverage tables, it gets really inefficient
 calling both functions for the dimensions instead of calling a unified
 ST_Dimensions function.
