Here is my query that's deleting all the records for the episode
DELETE FROM tracker WHERE tracker.episode_id = 238 AND
( rug_tracker.date_of_service < '09/12/2005'
OR rug_tracker.date_of_service > '10/20/2005' );
DELETE FROM tracker
WHERE episode_id = 238
AND date_of_service BETWEEN '2005-09-21'::date and '2005-10-20'::date;
Note that between is inclusive, so if you don't want Sept 21 (or is
it Sept 12? you've used one in your explanation and another in your
SQL) and Oct 20, you can use BETWEEN '2005-09-22' AND '2005-10-19'
instead.
