| Goal | This query identifies all views against which data modification statements (INSERT, UPDATE, DELETE) can be executed without raising an error. It evaluates the is_insertable_into and is_updatable attributes to detect both "naturally" updatable views (where PostgreSQL automatically maps changes to base tables) and views made updatable via the rewrite rule system (specifically DO INSTEAD rules). Notably, this definition encompasses views defined with DO INSTEAD NOTHING rules; while such views do not physically modify data, they are technically considered updatable because they accept DML statements without failure. |
