RETURNING * does not work correctly with INSERT/UPSERT #15551
Description
When INSERT is used together with RETURING * the operator has a strange behavior
CREATE TABLE `/local/test` (
id Uint64,
name Text,
PRIMARY KEY (id)
)Such a query returns Result(0)
INSERT INTO `test`
(`id`)
VALUES (1) RETURNING *;
In this case, if you add name to the query, the operator starts working as expected
INSERT INTO `test`
(`id`, `name`)
VALUES (999, 'f') RETURNING *;
UPSERT also works strangely, at the first insertion RETURNING does not work, but at the next one it already works
UPSERT INTO `test`
(`id`)
VALUES (555) RETURNING *;
