Comment (by robe):

 okay this is not just a sorting issue.  It seem the multiple calls of the
 function triggered by:


 {{{
         (ST_DumpValues(rast)).*
 }}}


 is actually creating duplicate records (one for each column). Even though
 people aren't supposed to do that because it does call the function for
 each column output by the (.*), I suspect this was an unintentional change
 in behavior in PostgreSQL 9.6.

 I could just change the tests to pass, but instead I'll complain upstream
 first to confirm they did intend this behavior change.
