Uh, well, we never call it ourselves, so if we don't expect other
applications to call it, why is it there?

Our code has:
	
	/*
	 *     Used to set callback that prevents concurrent access to
	 *     non-thread safe functions that libpq needs.
	 *     The default implementation uses a libpq internal mutex.
	 *     Only required for multithreaded apps that use kerberos
	 *     both within their app and for postgresql connections.
	 */
	typedef void (*pgthreadlock_t) (int acquire);
	
	extern pgthreadlock_t PQregisterThreadLock(pgthreadlock_t newhandler);

We need to research why it was added.
