Hi,
Just found $SUBJECT involving time with time zone and a subselect. I
still don't have narrowed to the exact table/index minimal schema but
if you run this query on the regression database it will creash.
```
update public.brintest_multi set
timetzcol = (select tz from generate_series('2021-01-01'::timestamp
with time zone, '2021-01-31', '5 days') tz limit 1)
;
```
attached a backtrace. Let me know if you need extra information.
