Hello:

I have a table with pluviometrical data

meteo (rain float, day date)

I want to select the the day of maximum value for each year.It should be
something like :


select max(rain),day from meteo group by date_part('year', day);


but it obiously doesn't work.
I thought of doing it with aggregates, but it's far too complicated. Is
there an 'easy' way to do this?
