Philip,
You can find the "patch so far" at:
http://services.csl.co.uk/postgresql/
along with a libpq thread-safe patch.
The thread referenced by Bruce's email details some of the issues
still to be looked at. The main work is integration with the build
system (testing for and linking in POSIX threads) and testing.
I'm more than happy for you to look at at, I haven't had the time I
hoped to complete this.
Thanks, Lee.
