Does PostgreSQL cache execution plan of a view

Question

Does PostgreSQL cache execution plan of a view, as it does for stored procedures?

Answer 1

No.

A view is basically a macro - your view definition gets merged with the query against it and then executed.

So:

CREATE VIEW v1 AS SELECT * FROM customers WHERE active;
SELECT * FROM v1 WHERE name LIKE 'A%';

becomes:

SELECT * FROM customers WHERE active AND name LIKE 'A%';
