You're right. The problem is whether the existing footings for the existing posts would be adequate to support the additional weight of added post length plus the weight load of the pergola framing and "roof." An additional issue is whether the underdecking (deck framing) would be strong enough to carry that additional weight load as well. I would guess - no, they're not. Do you know any structural engineers who will give you free advice? If not, I would ask around and hire one to scope out whether your project is feasible and what you might be able to do short of tearing everything out and starting all over again to get a deck with a pergola on top. Good luck, Bill.
