Query failure when reading from $partitions when Iceberg table partitioned on timestamp with time zone

[findepi]

Surely, this is far from common use-case, but still...

CREATE TABLE t2 (x timestamp(6) with time zone) WITH (partitioning = ARRAY['x']);
INSERT INTO t2 VALUES TIMESTAMP '2021-10-31 00:30:00 UTC',  TIMESTAMP '2021-10-31 01:30:00 UTC',  TIMESTAMP '2021-10-31 02:30:00 UTC', TIMESTAMP '2021-10-31 03:30:00 UTC';
SELECT * FROM "t2$partitions";
