Let's say I have a view like this:

CREATE VIEW v_small AS
SELECT c1, c2
FROM t1 JOIN t2 ON t1.c1 = t2.c2

and then I have another view

CREATE VIEW v_big AS
SELECT c1 FROM v_small WHERE c2 > 5

Now, when I do this:

SELECT * FROM v_big WHERE c1 < 1500

Is postgres going to make one query plan, or each view has it own query
plan?
