I'm keep getting composite type (row) instead of two columns. Is there any sql way to convert the row type into two columns ? I want to get the first and last dates of each quarter with those columns and with this composite type I failed doing it
This seems to work as you expect:
select distinct extract(year from end_time) as year, extract(quarter from end_time) quarter from generate_series ( '2017-09-01'::timestamp , '2019-04-01'::timestamp , '3 month'::interval) end_time ;
