Bug reference: 17832
Logged by: Marko Tiikkaja
Email address: marko(at)joh(dot)to
PostgreSQL version: Unsupported/Unknown
Operating system: Linux
Description:
Running the following query in HEAD fails with the error in $SUBJECT:
SELECT 1
FROM
(
SELECT NULL::text AS AccountName
) Actual FULL JOIN (
SELECT text 'foo'
UNION ALL
SELECT text 'bar'
) Expected (AccountName)
ON TRUE
WHERE Expected.AccountName IS NULL;
I tried PGv15 online and it seemed to work there, so I'm guessing this only
applies to HEAD.
