> 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.
