I suspect Doug's put his finger on the problem --- are you trying to
use the same PGconn object in both threads? Not a good idea at all.
libpq isn't thread-aware (mainly because of the portability problems
that would ensue), and it *will* break if you try to use the same
PGconn concurrently in two different threads.
