This seems like a solution in search of a problem to me.  The most
salient aspect of such processes is that they would necessarily run
as the postgres user, which means that you could never run any untrusted
code in them.  That cuts the space of "user problems" they could solve
way down.

I still haven't seen a good reason for not using cron or Task Scheduler
or other standard tools.
