Many thanks for all the investigation and fix!
Sadly, I have *no* idea what could have happened that would have caused
a connection at that point (my start scripts don't do it). It is
possible that I had a terminal running some shell loop on psql ("watch
psql -c something" perhaps). But I'm sure I didn't notice that when I
reported this, or I would have mentioned it. However, I have no idea
why would it have died with code 15. From my notes of what I was doing
that day, I can't find any evidence that I would have had anything in
shared_preload_libraries. (I don't have Frost's complete timestamped
shell history, however.)
