INFO is mostly a hack to try to emulate VACUUM VERBOSE's ancient
behavior before we redesigned the elog levels. It's intended for
controlling messages that should go to a client because the client
asked for them, and usually should NOT go to the log. I think it's
100% inappropriate to use it for messages from a background process
that has no client.
