What Tidybuoy said.
The dimension of the posts is not the failure point. Over time, stringers to which the pickets are nailed may sag if they span 8 feet. Shortening the dimension of each fence panel to 7 feet will improve longevity far better than increasing the diameter of the posts.
And no wooden fence made of conventional materials is going to last 100 years.
