Adrian, He never stated what the O/S is. I strongly suspect that he is using PgAdmin to connect to a remote server, which adds another degree of complication. So at the very least, we also need to know if the server is local or remote and what the O/S is. Plus, as you have requested before, exactly what time is "a long time"?
