Thanks.
I found that the patch was broken by commit f452aaf7d (the part
"adjust poll_query_until to insist on empty stderr as well as a stdout
match").
So I had to remove a "RAISE NOTICE" (which was just an informational
message) from the login trigger function, to satisfy the new
poll_query_until expectations.

Does it mean that "RAISE NOTICE" should’t be used, or behaves unexpectedly in logon triggers? Should we mention this in the docs?

Also, I updated a PG14 version check (now must check PG15 version).
