I found that the autovacuum launcher continues to run and spawn workers
after reloading the configuration file with autovacuum = off in CVS HEAD.
What should we do after autovacuum is disabled runtime? I think the
launcher should not spawn any new workers. It can be fixed easily,
but there are some other issues to be discussed:
- Can the launcher exit immediately?
or it needs to wait for all worker's exits?
- Should the workers skip the remaining jobs?
One difficulty is that workers ingore SIGHUP signals currently.
- Should the workers skip the table being vacuumed then?
