Hey Gary when I built my deck our support posts actually have an aluminum base that bolts to top of the flush filled footing. The base has a 1” air space designed right into the structure to keep the treated post dry, and NOT touching the concrete. It is designed to anchor the post but prevent rot…and yes treated lumber will eventually rot. Sent away a whole pile of the old deck, all treated, some rotted. New bases, bolt to concrete footing, slide in the post, use deck nails to secure the post to the anchor. The 1” airspace between wood post (treated) and the concrete is to promote air flow and keep the wood dry. Doesn’t matter if it’s treated it will rot if exposed to moisture and not allowed to dry out. That was code here. And I have no intention of redoing this deck for a LONG time.

Money cannot buy you happiness, but it can buy you a trapping license and that's pretty close.

Concrete in a post hole for a wood post should be used as a pad only. Dirt tamped solid for backfill. Concrete around a wood post will speed rot. Been doing it that way for many, many years.
Dry concrete in post holes for metal posts is fine and seems to be a very popular method with fence companies.
Over the past ten years or so I have been using the Simpson Stand Off's similar to what janNE shows above. I dig the holes, stick in a SonaTube so it's a bit above grade and sink an anchor bolt. After the concrete cures the Stand Off's get attached.
The Simpson Stand Off's, the heavily galvanized ones, are spendy but, IMO, well worth the money, no wood in contact with the ground.
Eh...wot?

I'm in Arkansas where there's more rock than dirt and I'm not excited about digging deep holes, especially if the posts are gonna rot.

After I retired from grazing cattle, I removed all my high tensile wire, steel T posts and pressure treated wood fence posts. Regarding rot to posts, 90% of the rot occurs in the top 8 - 10" of soil. About halfway through building my fences, I began backfilling and packing the posts with limestone gravel. Years later many of them hardly showed any sign of being in the ground at all. If nothing else, pre-treat the post with a decent oil based stain, just the 12" that will be from the soil surface and down. My short stint with pole barn builder back in late 1970s. All the large barn post where set in hole on 6 inch thick concrete pad. Then we tamped in the lime rock gravel in around them gets almost like cement. I'm guessing it Is same rock TraderVic used.. I don't know what those post look like up close now. But those building are still standing. Mac

Interesting that there is no consensus on the right way to do this.

I think we've established that concreting wood posts into the ground is bad, setting them on concrete pads and back-filling with dirt or gravel is better and not putting them in ground contact by using concrete pillars and stand off's is best.
Eh...wot?

If you put wood in ground just slather it up with creosote and provide crushed rock in the hole for drainage-last longer than you will.
