I agree, and if I had a copy of 10+ running, I probably would have! :)

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!
Ken
