OK, it took me a while to figure this out, but it is similar to the
problem we have on AIX. AIX shared libraries don't track other
libraries needed by the shared library, and non-shared libraries also
have no such dependency information.
I have attached a patch that is very similar to the AIX fix. It
basically propagates the thread library flags to all uses of libpq.
Would you please test and report back? Thanks.
