1. Trim Schema Names: Adapted the system to remove trailing spaces from DB2 schema names, ensuring compatibility without affecting query operations.
2. XML Mapping: Implemented a feature to directly map XML types to String.
When ifnull or nvl funtion have only one parameter, nereids planner would throw an exception and go back to
original planner/ Original planner get secend parameter directly without check, so it return unexpected error message
This PR #23026 support the partition prune for hive table with `_HIVE_DEFAULT_PARTITION`,
but it will always select partition with `_HIVE_DEFAULT_PARTITION`.
This PR #31613 support null partition for olap table's list partition, so we can treat `_HIVE_DEFAULT_PARTITION`
as null partition of hive table.
So this PR change the partition prune logic
Problem:
When partially updating columns without specifying the auto-increment column, and the imported data contains new keys, an error stating the auto-increment column could not be found occurs.
Reason:
The logic for partial column updates does not account for new keys in auto-increment columns. Since auto-increment columns can be generated by the system, it's possible to omit this column data during import. However, partial column updates treat this as a regular column, expecting it to be nullable or have a default value for automatic filling, overlooking the fact that auto-increment columns can also be auto-filled. This oversight leads to the error.
Solution:
Incorporate a check for auto-increment columns into the partial column update logic, and include the logic for generating auto-increment column values in the process of completing partial updates.

It supports predicate composite as following:
materialized view define
> select l_shipdate, o_orderdate, l_partkey, l_suppkey
> from lineitem_1
> left join orders_1
> on lineitem_1.l_orderkey = orders_1.o_orderkey
> where l_shipdate > '2023-10-19'
the query as following can be rewritten by the materialized view above
> select l_shipdate, o_orderdate, l_partkey, l_suppkey
> from lineitem_1
> left join orders_1
> on lineitem_1.l_orderkey = orders_1.o_orderkey
> where l_shipdate > '2023-10-25'
When left join with no edge in outer side, we should add outer side to minimal require of left tables

When compaction, if some segments miss variant root, there is chance to get emtpy root variant.So add some defence
code in OlapColumnDataConvertorVariant to prevent from accessing null root
