I realize I'm jumping into the middle of this with something unrelated.
My apologies. A feature I've wanted a couple of times and which I know
other people have asked for is being able to schedule tasks to run at
certain times. Similar to cron or scheduler, but in the database
instead of having to set up something outside.

I would expect it to use something similar to the autovacuum
launcher/worker system. I'm wondering if it would be possible to
consider how other autovacuum-like systems might be added in the future
when doing these changes.

Thanks,

Stephen
