emaktech c97d9e7022 Order by start_epoch to Speed Up Query Execution ...

In some cases, this seems to speed up xml_cdr loading times by ~10x.

It appears one big cause of this is the final ORDER_BY statements are very slow in PostgreSQL for timestamp fields. Ordering by start_epoch field improves query execution time in a dramatic way and should result in the same ordering.
