Hmm.  According to the commit log entry mentioned in that thread:

  r224016 | bz | 2011-07-14 14:18:14 +0000 (Thu, 14 Jul 2011) | 10 lines

  Remove semaphore map entry count "semmap" field and its tuning
  option that is highly recommended to be adjusted in too much
  documentation while doing nothing in FreeBSD since r2729 (rev 1.1).

So it seems like rather than adding text to the effect that semmap is
gone in 9.0, we should probably stop suggesting that it be adjusted
altogether, regardless of FreeBSD version.

            regards, tom lane

Node.Thanks for your work!
