When it comes to 'who can set it'- my first reaction is "the owner".
The next question is- what rights does the owner have to have on the
"other-user" role, and I would suggest "membership". This could be
extremely useful for non-C functions as well, consider this:
I'm Bob. I have an 'audit' role which is granted to me. I'd like to
create a function that runs as 'audit' (which has various rights granted
to it which are less than the rights of 'Bob'), but which only I can
modify. If I've been granted the 'audit' role, then I can create a
function which is owned by 'audit' (set role audit; create function
...), and I could make it security definer, therefore I should be able
to create a function which is owned by me and runs as 'audit'.
Writing this a bit off-the-cuff, so apologies if there are obvious flaws
in this logic. :)
Thanks,
Stephen
