Hi,
After commit ca307d5, I noticed another crash when testing
some other logical replication features.
The server with max_replication_slots set to 0 would crash when executing CHECKPOINT.
TRAP: failed Assert("ReplicationSlotCtl != NULL"), File: "slot.c", Line: 1162, PID: 577315

I think it is trying to access the replication slots when the shared memory
for them was not allocated.
Best Regards,
Hou zj
