Well, the big question is how many people have a non-default
vacuum_cost_delay, since it defaults to zero. If someone has changed
the default (a small percentage), how many of those will be confused by
PGOPTIONS? At that point, it seems unnecessary. Also consider that a
new option will only be useful for those who have non-default
vacuum_cost_delay values, which can also be confusing.
