Not sure about the "cancel vacuum full" question, but I had some other thoughts
for you.
Keep in mind that a plain vacuum can do a lot of good if done regularly, and
it doesn't lock tables, thus the database can be in regular use while it's
run. As a result, there is no downtime involved with regularly scheduled
vacuums.
There _can_ be a performance hit while vacuum is running, so you may need to
take that into account. But I would expect that the performance hit incurred
during running vacuum will be less than that of not running it for long
periods of time.
