Buildfarm member hoverfly stopped reporting in when this test joined the tree.
It's currently been stuck here for 140 minutes:

===
$ tail -n5 regress_log_035_standby_logical_decoding
[02:57:48.390](0.100s) ok 66 - otherslot on standby not dropped

### Reloading node "standby"

I've posted a tarball of the current logs at
https://drive.google.com/file/d/1JIZ5hSHBsKjEgU5WOGHOqXB7Z_-9XT5u/view?usp=sharing.
The test times out (PG_TEST_TIMEOUT_DEFAULT=5400), and uploading logs then
fails with 413 Request Entity Too Large.  Is the above
log_min_messages='debug2' important?  Removing that may make the logs small
enough to upload normally.
