Avoid passing zero as a value for vacuum_cost_limit, because it's not a valid
value for the vacuum code. Instead, make zero signify getting the value from a
higher level configuration facility, just like -1 in the original coding. We
still document that -1 is the value that disables the feature, to avoid
confusing the user unnecessarily.
