Are the posts wood?

From the below link (1/4 of the way down)...

[Another serious problem is occurring concerns support posts and footings.
When support post are put into the footing, and even the ground, they are
prone to rot. Even pressure treated posts, including 6x6's may completely
fail within a few years.

The problem occurs when the post is put into the ground, and concrete is
poured around the post. Once the concrete has set, the post has established
a pocket in which water can collect. The water is absorbed into the post
and cannot dry out. In colder climates the water freezes and can crack the
concrete. Additionally, the deck should be bearing on top of the footing
and not in it. Some people are under the misconception that pressure
treated wood will not rot. ]

Hello,

I am building a pool deck and want to place a 15'x18' cabana (four
columns, roof) on top of it. The cabana is held up by 8x8" posts and
has a shingled roof. My question is because the cabana company wants
to have the pool company pour the deck, making it a bit thicker where
the posts will be, and then use concrete anchors to anchor the posts
to the pool deck. The pool company thinks they should place the posts
before they pour the deck so they are set in the concrete instead,
making it sturdier...any opinions?

Thanks,
