Just for the record, with the same "cities" table as my original post
to this thread, this query:
select count(distinct(city)) from cities;
Goes from taking about 296ms (once it stabilizes), to about 265ms
(once it stabilizes) following today's commit of just the unsigned
integer comparison patch. I've shaved just over 10% off the duration
of this representative sort-heavy query (against a 9.5 baseline),
which is nice.
