Building a pergola on top of a deck is a bit more complex than building directly on the ground. When you build on the ground, you can bury your posts in the ground and use gravel, dirt, or concrete to give them more stability. On a deck you’re going to need to connect wood to wood, which can potentially make the pergola less stable.
A pergola of a larger size will require more support and that means more posts. The weight of the beams, joists and any cladding will all be resting on the posts so your site must have adequate clearance for support. The posts must be able to be dug in with adequately planned foundations, or you're in for a lot of heartache.
An older deck may be ill-equipped to support the weight of a pergola, so this may be a good opportunity to replace your decking or deck posts with newer lumber. Decks over 15 years old or those constructed of untreated lumber are at higher risk of failure.
If the weight of a pergola is going to threaten the structure then the deck should be rebuilt. (There is a danger, though, of the pergola being torn off in a high wind and causing collateral damage. Whatever anchorage is used needs to be able to withstand substantial uplift, and this may mean somehow reenforcing deck planking fasteners to ...
Most deck builders bolt pergola support posts to the frame of the deck using (2) 1/2" x 6" lag screws with washers per post. This technique is the same as attaching a rail post. Pergolas are top heavy. Without lateral bracing, they can sway in the wind and experience strong uplift forces as the pergola acts as a sail.

A couple of years ago I built a deck onto my house. It is 32' x 14' I used a cantilever design at 12' with 2x8" floor joists, with 2x6" decking boards. The Cantilever beam was set on 6x6" posts that are on top of 30" deep footers. I doubled up a 2x12" for the cantilever beam by notching the 6x6" on either side, and putting the 2x12 in each notch.
Pergolas are structures that provide shade over a deck or a patio during the summer months. A pergola can be a free standing structure or you can construct one that attaches to the side of your house. Building an attached pergola, 16 feet by 20 feet, on your deck can be done by first determining if your deck is big enough for this size of pergola.
