The text abbreviation code has a compile-time option to emit DEBUGn elogs. I made no attempt to add these to the numeric abbreviation code because I find such things completely unhelpful; when you need to investigate such things other than in initial development, it's unlikely that you will be in a position to recompile. Also, as I showed at some length earlier, even recompiling with an apparently irrelevant change can have enough of an effect on performance to make investigation more complex.
So if these debugging elogs are to be kept at all, I propose that rather than being compile-time options they should be controlled by a debug_sortsupport GUC.
