Since each logical connection always requires a logical replication slot, the actual number of active logical connections (and logical WAL senders) would ultimately be bounded by max_logical_replication_slots. My main concern is therefore slot exhaustion rather than the WAL sender limit. -- Ahmed Et-tanany Aiven: https://aiven.io/
