I would like a way to run the autovacuum daemon on demand

Anybody know if this is possible? If not, it's a feature request :-)
Autovacuum can be enabled / disabled on the fly using the GUC settings.
Perhaps you can write a cron script that runs at 2AM that enables
autovac, and at 6AM (just a guess) disables it in the same fashion. I
think that should work.
Would be curious to hear your results.
I thought it sounded like a good idea, but then...
SET autovacuum = on;
ERROR: parameter "autovacuum" cannot be changed now
So then I thought maybe I could kind of fool it with...
SET autovacuum_vacuum_threshold = 99999999;
ERROR: parameter "autovacuum_vacuum_threshold" cannot be changed now
Oh well.
