Hmm ... actually, I don't think the max_connections parameter is used
during standalone operation.  It looks like the code uses a hardwired
value of "16".  We could reduce that (there's probably no good reason
why it's not "1"), but I suspect your SEMMAX parameter is so small
it will fail anyway :-(

Would you try changing "16" to "1" in InitCommunication() in
src/backend/utils/init/postinit.c, and see if that helps on your
setup?
