I've found first solution using WINDOWING:

SELECT d.pintime, d.a_id, d.c_id, d.value, d.id, d.sincedate,
d.todate, d.description, d.genre
FROM (SELECT pintime,a_id,c_id,value,id,sincedate,todate,description,
genre, $1::date-a.sincedate as days, min($1::date-a.sincedate) over w AS
"days 2"
FROM b, a
WHERE pintime BETWEEN $2 AND $2::interval+'00:01:00'::interval
AND b.a_id=a.id AND a.genre='F' AND description ~*'35$'
WINDOW W AS (partition by c_id)
ORDER BY $1::date-a.sincedate ASC) AS d
WHERE d.days=d."days 2"
ORDER BY d.c_id;

I'm sure that there are many other solutions and probably mine could be
not the best. So I'm looking for more hint and suggestions.

Thank you again. \ferz
