Is it time to "remove" PG qsort and use libc version for solaris 9, 10...?


I have no particular desire to introduce a version number check until we
have to.  If you can show that the newer versions have a qsort that
substantially *out-performs* ours, it would be worth doing that, but
merely being competitive isn't enough to make it worth the trouble.


The implementation in the solaris uses same ideas like postgres implementation exclude sort array detection. There are small difference with threshold when median uses 9 items and threshold for insertion sort. Performance is similarly - no winer (only on sorted array).
