-- Convert soaking duration to hours instead of minutes
-- 1) Rename column
ALTER TABLE public.soaking RENAME COLUMN soaking_duration_minutes TO soaking_duration_hours;

-- 2) Change type to double precision to allow fractional hours
ALTER TABLE public.soaking ALTER COLUMN soaking_duration_hours TYPE DOUBLE PRECISION USING soaking_duration_hours::double precision;

-- 3) Convert existing data (currently minutes) to hours
UPDATE public.soaking SET soaking_duration_hours = soaking_duration_hours / 60.0;

-- 4) Ensure CHECK constraint (> 0)
ALTER TABLE public.soaking DROP CONSTRAINT IF EXISTS soaking_soaking_duration_minutes_check;
ALTER TABLE public.soaking ADD CONSTRAINT soaking_soaking_duration_hours_check CHECK (soaking_duration_hours > 0);
