короче типа такого SELECT DISTINCT ON (vh.offset) vr.rate FROM statistic.video_rate vr LEFT JOIN statistic.video_position_history AS vh ON (vr.language = vh.language AND vr.country_id = vh.country_id AND vr.device = vh.device AND vr.tag_id = vh.tag_id AND vr.video_id = vh.video_id) WHERE vh IS NOT NULL AND vr.language = ?0 AND vr.country_id = ?1 AND vr.device = ?2 AND vr.tag_id = ?3 AND vh.page = ?4 AND vh."limit" = ?5 AND vh."offset" IN (?6) ORDER BY vh.time DESC, vr.rate DESC
