This issue only comes with Iceberg tables when using partitioned by instead of
partitioned by spec. The following statements work as expected:
creating non-Iceberg table:
create table t partitioned by (p) as select cast(1 as int), cast(1 as int) p;
using partitioned by spec instead of partitioned by:
create table t partitioned by spec (p) stored as iceberg as select cast(1 as
int), cast(1 as int) p;
