I agree with Andres' point about this: sometimes it'd be more convenient
for an advisory lock to be released automatically at transaction end.
If you have a mix of clients that want that behavior with others that
want a persistent hold on the same locks, you can't do it with regular
locks.
Right. And that's why they need to be in the same lockspace.
