My concern was that I wanted to make sure that whatever I did was available to the backend, and in the presence of exec/CreateProcess I would need either to make sure it got passed to the backend if done before, or to make sure that it was done after. That's why I wanted to have the sequence of events clear in my head. cheers andrew ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
