I have to agree with Island here. There's almost no weight on this structure, so I would just drill and anchor a "clip" to hold the post and build the thing. That slab should be about 3.5" typically. Any less then that, saw cut and pier may be necessary.

don't put that post right on the edge of the slab if you are trying squeeze most out of the space there. Come in 8-10". If you go beyond the slab, then dig out a hole and pour a pier and install a metal connector to the post. I like a 6x6 base on looks. it just look so much more robust compare to a 4x4.
