Why not? What would be needed to retarget a backend to operate in
another database?

Such a retargetting would be helpful in several cases:
- pre-forking of backends (well, depends on efficiency of
retargetting..)
- slave backends for parallel query execution
- slave backends for replaying replicated transactions

I'm using backends operating without a client connection, with superuser
privileges only. But those are still connected to one specific database.
It would really be helpfull if I could retarget them as needed.
