Help with an interesting Postgres question: Why isn't an Index Only Scan used on a partition accessed via the parent table?.
CREATE TABLE j_play (
id serial PRIMARY KEY,
created_ts TIMESTAMPTZ,
data JSONB
);
CREATE TABLE
insert into j_play (data) values(null);
update j_play set data = coalesce(data, '{}') || '{"a": "12345"}';
update j_play set data = coalesce(data, '{}') || '{"b": "54321"}';
select * from j_play;
INSERT 0 1
UPDATE 1
UPDATE 1
| id | created_ts | data |
|---|---|---|
| 1 | null | {"a": "12345", "b": "54321"} |
SELECT 1
