So it sure looks like this script does expose a problem on BSD-derived qsorts. Curiously, the case that's much the worst for me is the third in the script, while the shortest time is the first case, which was slow for Gary. So I'd venture that the *BSD code has been tweaked somewhere along the way, in a manner that moves the problem around without really fixing it. (Anyone want to compare the actual FreeBSD source to what we have?) It's really interesting to see a case where port/qsort is radically worse than other qsorts ... unless we figure that out and fix it, I think the idea of using port/qsort everywhere has just taken a major hit.
More specifically to BSD, is there any way I can use a non-BSD qsort for building Postresql server?
