I believe in 'when it doubt try it, whats the worst that can happen?:)':
I agree, and if I had a copy of 10+ running, I probably would have! :)
<NOTE> I needed to be a superuser to run due to this:

Maybe I'm missing it, but I'm not really sure what that is supposed to be telling me about the ownership of the sequence.
The scenario I'm wondering about is:
Table A owned by User 1, and has column created as serial
The created sequence is altered to be owned by User 2 (with User 1 granted select & update)
upgrade_serial_to_identity applied to Table A
At that point, who owns the sequence?
I can wait until I've got 10+ running and try it myself, but I thought maybe someone would know the answer and be willing to share.
Thanks!
