TIMESTAMP '...' describes a timestamp literal. If you wanted to explicitly cast the value in good_date as a timestamp, you'd probably want CAST(good_date AS TIMESTAMP). If good_date is of type date, however, I believe the cast to timestamp is implicit, so you should probably be able to just use extract(epoch from good_date).
