Using v11 I'm getting this error:

~/pgsql took 22s
✦ ➜ pg_createsubscriber -d fabrizio -r -D /tmp/replica5434 -S 'host=/tmp
port=5434' -P 'host=/tmp port=5432'
NOTICE:  changed the failover state of replication slot
"pg_createsubscriber_16384_706609" on publisher to false
pg_createsubscriber: error: could not drop replication slot
"pg_createsubscriber_706609_startpoint" on database "fabrizio": ERROR:

Attached the output log.
