Well, you're sorting numeric here, no? Why should it matter that a
datum sort has abbreviation support, if the underlying type (numeric)
does not support abbreviation? OTOH, why should having oplcass
abbreviation support (for numeric) matter if the class of tuple sorted
(datum "tuples") does not support abbreviation? You need both to
meaningfully benchmark either (as long as you're looking at a case
involving both).
I suggest looking at datum sorts with text for the datum sort patch,
and non-datum tuplesort cases for the numeric patch, at least until
such time as one or the other is committed.
