Special Cases

Redshift seems to have a bug where it will overflow when asking day ranges that become too negative, typically due to faulty columns that have bogus dates like "Nov 1 2065" when referring to values that should be around now.

Keep in mind we do not know exactly how the bug occurs; this is a guess based on what we've seen in a one-off edge condition.
