There's no really good reason why the autovacuum launcher and logical replication launcher should announce themselves at startup and shutdown by default. Users don't care that those processes exist, and it's inconsistent that those background processes announce themselves while others don't. So, reduce those messages from LOG to DEBUG1 level. I was sorely tempted to reduce the "starting logical replication worker for subscription ..." message to DEBUG1 as well, but forebore for now. Those processes might possibly be of direct interest to users, at least until logical replication is a lot better shaken out than it is today.
