The following bug has been logged on the website:
Bug reference: 17479
Logged by: Michael J. Sullivan
Email address: sully(at)msully(dot)net
PostgreSQL version: 14.2
Operating system: Linux
Description:
The following query produces "plan should not reference subplan's
variable"
create table Card (id uuid);
SELECT
-- This line causes "variable not found in subplan target list"
-- grouping(res.cnt)
-- This line causes "plan should not reference subplan's variable"
(SELECT grouping(res.cnt))
FROM Card
CROSS JOIN LATERAL
(SELECT
(SELECT Card.id) AS cnt
) AS res
GROUP BY
res.cnt
As the comment says, a slight change instead errors with "variable not found
in subplan target list".
