I everybody, I'm new in the Postgresql world, and have an easy question: Is it possible to have date type data that only contain month and year?, how can I obtain that from a timestamp (without time zone) column?
I've made this, but I think the result is a text, not a date
select extract (Year from '2001-05-01 20:21:00'::TIMESTAMP WITHOUT TIME ZONE)||'-'|| extract(Month from '2001-05-01 20:21:00'::TIMESTAMP WITHOUT TIME ZONE);
