Description:

Hi, 
I am going through PostgreSQL, for the first day. And it was great till
now.
One quick question/doubt regarding the function "justify_days(interval)"

select justify_days(interval '365 days');

this statement returns  1 year 5 days, whereas I feel it should be just 1
year.

Please correct me if I am wrong.. Thanks for all your time.
