No problem:

---
class A
{
public:
    pqxx::result test(const std::string &rString, const std::string &rDesc = std::string()) // fatal error
//  pqxx::result test(const std::string &rString) // OK
    {
        return pqxx::result();
    }
    pqxx::result test1(void)
    {
        return pqxx::result();
    }
};
int main(int argc, char* argv[])
{
    A a;
    BOOST_AUTO(rs, a.test("SELECT 1")); // fatal error (when used A::test(const std::string &rString, const std::string &rDesc = std::string()))
...
}
---
So when I use the first signature (pqxx::result test(const std::string &rString, const std::string &rDesc = std::string()) there is fatal error. Otherwise everything compile OK.

std::cout << typeid(T.exec("SELECT 1")).name() << std::endl;
Output:
class pqxx::result
