OK, I have found the problem. It turns out to be in the way that it is
built under the NetBSD pkgsrc system. As soon as a module is loaded
that uses pthreads it sets a variable (__isthreaded) that causes the
above error. The answer is to simply link PostgreSQL with -lpthread to
begin with. We are making some changes to the pkgsrc system to do this
correctly with this and some other packages that could potentially have
the same problem.
Thanks for the help in finding this.
