The entire point of a replication slot is that it prevents WAL from
being discarded until whatever is supposed to read from the slot
has consumed that WAL. So apparently nothing is reading from that
slot, which means there is something wrong with the way
you've connected up your replication setup. I would have thought
you'd be using slots to feed your standby and witness servers
(and I don't understand why you don't have two slots, one for each).
