Hello,
after upgrade from PG11 to PG14.8 the following statement started failing:
select
a::BIGINT
FROM (
SELECT
'$maybeNumber'::VARCHAR AS a
WHERE NOT '$maybeNumber' LIKE '%maybeNumber'
) AS foo;
Expected (as in PG11): The query should return empty result with one column.
Actual: SQL Error [22P02]: ERROR: invalid input syntax for type bigint:
"$maybeNumber".
Where is a workaround that shows the behavior is quite non-stable.
Following passes normally while still using the same subquery with one
more empty result from another one:
select
a::BIGINT
FROM (
SELECT
'$maybeNumber'::VARCHAR AS a
WHERE NOT '$maybeNumber' LIKE '%maybeNumber'
UNION
SELECT '0' AS a WHERE false
) AS foo;
Thanks all for the great work you do on PG.
