Dave,
i wonder if we should aim to have pgAgent in the backend which was one
of the reasons why I considered to have it converted from C++ to pure C.
There are many regular maintenance issues that AV can cover, some more
it could cover and many more we can't even think of right now. Having an
sql executing agent freely at hand (consistent on _every_ platform,
without cron/anacron/at/younameit dependencies) should be helpful for that.
