Comment(by dustymugs):

 As for a coverage version of ST_Quantile, one has yet to been written due
 to potential memory issues.  The problem is that all quantile functions
 require all values loaded and sorted.  So, I need to see if I can only
 load subsets of values around the quantiles to be returned.
