Doesn't this also imply recovery conflicts on DROP DATABASE? Besides,
allowing to drop all slots using a database upon DROP DATABASE, is a
useful thing on its own.
But I have to admit, I've *severe* doubts about getting the whole
infrastructure for slot creation on replica into 10. The work is far
from ready, and we're mere days away from freeze.

That pretty much requires decoding, otherwise you really don't know how
much WAL you have to retain.
