Ah, we can separate the proposal to two topics:
A. Support to run non-vacuum jobs from autovacuum launcher
B. Support "user defined background processes"

A was proposed in the original "1 of 6" patch, but B might be more general.
If we have a separated coordinator, B will be required.

Markus, do you need B? Or A + standard backend processes are enough?
If you need B eventually, starting with B might be better.
