After multiple attempts, I got one failing one.
Issue is that we expect this file to be removed:
[07:24:27.261](0.899s) #WAL file is
/Users/admin/pgsql/build/testrun/recovery/035_standby_logical_decoding/data/t_035_standby_logical_decoding_standby_data/pgdata/pg_wal/000000010000000000000003
But the standby emits:
2023-05-05 07:24:27.216 UTC [17909][client backend] [035_standby_logical_decoding.pl][3/6:0] LOG: statement:
checkpoint;
2023-05-05 07:24:27.216 UTC [17745][checkpointer] LOG: restartpoint starting: immediate wait
2023-05-05 07:24:27.259 UTC [17745][checkpointer] LOG: attempting to remove WAL segments older than log file
000000000000000000000002
So it seems the test is not right (missing activity??), not sure why yet.
