Surely I'm missing something, but maybe this is something to work on:
WITH
RECURSIVE months(number) AS ( SELECT 1 UNION SELECT number + 1 FROM
months WHERE number < 12 )
SELECT m.number, s.id, s.name, count( h.state_id )
FROM state s JOIN history h ON s.id = h.state_id
JOIN months m ON m.number = date_part( 'month', h.ts )
