Is backup part of this new privilege, or not?
I think if we're going to introduce a new level of privilege, then we
should introduce all delegatable privs in one software release. Much
better than having someone think up a new delegatable priv each release
for next 5 years.
Other possible ones include unsafe PL creation, seeing logged SQL etc..
