Bug reference: 18277
Logged by: Zuming Jiang
Email address: zuming.jiang@inf.ethz.ch
PostgreSQL version: 16.1
Operating system: Ubuntu 20.04
Description:
My fuzzer finds a bug in Postgres 17devel, which triggers an unexpected
error "ERROR: WindowFunc not found in subplan target lists".
--- Set up database ---
create table exeet_t184 (vkey int4);
create view exeet_t188 as
select
ntile(ref_1.vkey) over w0 as c_1
from
(exeet_t184 as ref_0
left outer join exeet_t184 as ref_1
on (ref_0.vkey = ref_1.vkey))
where ref_0.vkey <> ref_1.vkey
window w0 as (partition by ref_0.vkey);
The fuzzer generates a test case:
--- Test case ---
select
(case when ('false' <> (SELECT nummultirange() && 'empty'::numrange)) then
(case when (1 in (
select
1 as c_0
from
exeet_t188 as ref_12
where 1 between ref_12.c_1 and 1)) then 1 else 1 end
) else 1 end) as c_5;
--- Expected behavior ---
The test case should not trigger any error.
--- Actual behavior ---
The test case trigger an error:
ERROR: WindowFunc not found in subplan target lists
--- Postgres version ---
