3: One process, multiple threads, all threads share the same one persitant connection. Because one thread serve one request in present time, but threads can run "concurently" (AFIAK ), I am affraid, that multiple transactions over the single connection in this scenario will result a complette mess. I am right ?
Yes - that's the definition of a connection really. Each connection provides you with a set of configuration values and a context for transactions.
