Help with an interesting Postgres question: Why isn't an Index Only Scan used on a partition accessed via the parent table?.
create table table11(
id serial primary key,
seconds int
);
insert into table11 (seconds) values
(15), (60), (60*60);
alter table table11 alter seconds type timestamp
using '2018-11-18'::date + (seconds||' seconds')::interval;
select * from table11;
