Ok, this makes perfect sense, kind of what I was saying only better.
The only thing I can add to it at this point is to reorganize the lock
view(s) correspondingly...should be 1 view for each specific lock type
plus 1 generic one for all locks. A new datum for the generic lock
type (plus some casts) might be worth considering.
Is it possible for one backend (with superuser privs) to release a lock
held by anotether?
