No, they won't have it, and things begin to get bad once a base backup
includes a slot that has a non-null value of restart_lsn. I imagine
that if we want to guarantee the correctness of a replication slot we
would need to fetch from archives the necessary WAL files needed for
it when a node is in recovery, which is not something that this patch
does...
