Description
Describe the bug
A clear and concise description of what the bug is.
To Reproduce
set allow_experimental_insert_into_iceberg=1;
attach table test UUID '0ff90094-cc91-442b-8da4-85bc504640c6' (datetime DateTime, value UInt32) engine=Iceberg(s3_conn, filename='test', format='Parquet') partition by toRelativeDayNum(datetime);
insert into test values ('2021-01-01 21:00:00', 1)
