1. this assumes there is only one holder, which is not correct.
(Consider two backends holding shared lock on something and another one
stuck trying to acquire exclusive)
2. I think pgstat_get_backend_current_activity() can be helpful.
3. Doesn't this risk excessive overhead? Can the other backends be gone
(or done with the lock) before the report has completed? If this
happens, is there a problem?
