For my comparison test of PG 12 and 13 I did not change any default setting except wal_level.
But I also did some tests and increased wal_keep_size and max_slot_wal_keep_size to 1GB. And I set wal_sender_timeout to 1h but without success. The setup works in PG 13 only with a small amount of data.
Best,
Henry

It kinda looks like something is timing out before it's managed to catch up with the (rather large) initial state of table t. What non-default replication settings are you using?
