Something like this:
SELECT period_num
, SUM(CASE WHEN home THEN shots_teama ELSE 0) AS shots_home
, SUM(CASE WHEN away THEN shots_teamb ELSE 0) AS shots_away
FROM periods
, matches
WHERE period.matchid = matches.id
AND matches.played
AND matches.origin = 1
AND matches.match_date between '2009-08-01' AND now()::date
AND NOT matches.training
GROUP BY period_num
ORDER BY period_num;
