> Occasionally, when entries are added to the partition stats table the program
> is halted before it can delete those entries, by an exception, keyboard
> interrupt, etc. These build up to the point where the table gets very large,
> and it hurts the performance of the update statement which is often called.
> In order to fix this, I am adding a column to the table which is
> auto-populated with the current timestamp. This will allow us to create
> scripts that go through periodically and clean out old entries from the table.
