RE: [CAUTION: SUSPECT SENDER] RE: BUG #19029: Replication Slot size keeps increasing while logical subscription works fine

Oh, I misunderstood like that number of WAL files increased.

Let me do some more questions to diagnose your system.
Can you share us the logical_decoding_work_mem on the publisher side? You can obtain via:
```
SHOW logical_decoding_work_mem;
```

Also, when you succeeded to reproduce, can you run the below command to see the
conent of the directory? ${DATA_PUB} can be tuned based on your environment.
```
du -sh ${DATA_PUB}/pg_replslot/*/*
```
This can see for which file uses the disk so much.
