Int to Interval conversion

  Hi everyone,

I have a table with a duration field, stored as an Integer. How can I
retrieve this from the table as an Interval type?

E.g.

create table test (test_id serial primary key, time_in_minutes int);
insert into test values (1440);

Now how do I extract that as 24:00:00::interval in a query?

Thanks.

Howard Cole.
