Depends on your logging level. I don't know that there is noticeable
difference between the two in terms of performance. That said, it is
still silly that we have to handle it in such a hacky way. Frankly, it
should be a catalog reloption of some sort... "ALTER CATALOG (which
doesn't exist) archive_mode TO off" but I digress.

I think it is because one launches a process that controls another
process. Just like autovacuum or the logger. You can change what the
children processes do but not the parent.
