[Query] Questions about hash distribution prunner.

[morningman]

Describe the bug

1. First to create a table with distribution key type DATE

create table tbl5 (k1 date, k2 int) distributed by hash(k1) buckets 3;

2. Insert one row

insert into tbl5 values("2020-03-20", 1);

3. Query like

select * from tbl5 where k1 = "2020-03-20";

This query will hit only bucket, which is expected.

And the following query:

select * from tbl5 where k1 = "2020-03-20 10:12:35";

Will also hit one bucket. Although it seems not results in wrong result.
But does it make sense?
