Well for me it's the difference between this:
australia=# \d affiliates_transactions
View "public.affiliates_transactions"
Column | Type | Modifiers
--------------+--------------------------+-----------
affiliate_id | integer |
date | timestamp with time zone |
type | text |
type_id | integer |
amount | numeric |
View definition: ((((((((((((SELECT palm_buyers.affiliate_id,
timestamptz(abstime(palm_buyers.datetime)) AS date, 'Palm' AS "type", 1 AS
type_id, palm_buyers.affiliate_amount AS amount FROM palm_buyers WHERE

NOT NULL))) UNION ALL (SELECT palm_buyers.affiliate_id,
