I'm not sure what the OP had in mind, but the thing which is missing for
us is a time window restriction sort of thing. What I mean is to make
sure a vacuum will never kick in in the main business hours, but only at
night at pre-specified hours, and only if the vacuum threshold was met
for the delete/update counts.
It would be nice if there could be a flexible time window specification,
like specifying only some days, or only weekends, or each night some
specific hours... but just one time window would be a big improvement
already.
