It's not really possible as rmgr.c declares a const array of resource managers. 
A contrib module can't sensibly add itself to that. I think changing this has 
been discussed/proposed in the past, but -hackers wasn't convinced...

But then, the idea is to add it to -contrib while no WAL support exists..

Personally I don't see a point in -contrib'ing it. I would rather see it throw 
errors in dangerous situations and be done with that.
