I need to a value associated to a month and a user in a table. And I want to perform queries on it. I don\'t know if there is a column data type for this type of need. If no
If you are interested in display values in YYYY-MM formt you can use to_char(your_datatime_colum,'YYYY-MM')
example:
SELECT to_char(now(),'YYYY-MM') as year_month
