…ng (#43263) Problem: Creating a view on a table with materialized views (MV) results in an error: failed to init view stmt. For example, executing the following SQL: create view v1 as select * from t1 index t_mv_mv. Root Cause: The syntax index t_mv_mv is supported only by the new planner and not by the old planner. During the view creation process, regardless of whether the new or old optimizer is used, the process eventually calls the createView method in Env. In the createView method, the persisted SQL of the view is parsed using the old optimizer's parser. If the parsing fails, an error is thrown. As a result, if the SQL for creating a view includes syntax supported only by the new optimizer, an error occurs. Solution: This PR addresses the issue by removing the parsing check from the createView method in Env. Instead, the check is moved to the respective classes responsible for creating views in the new and old optimizers.

What problem does this PR solve?
Problem:
Creating a view on a table with materialized views (MV) results in an error: failed to init view stmt. For example, executing the following SQL:
create view v1 as select * from t1 index t_mv_mv.
Root Cause:
The syntax index t_mv_mv is supported only by the new planner and not by the old planner. During the view creation process, regardless of whether the new or old optimizer is used, the process eventually calls the createView method in Env. In the createView method, the persisted SQL of the view is parsed using the old optimizer's parser. If the parsing fails, an error is thrown.
As a result, if the SQL for creating a view includes syntax supported only by the new optimizer, an error occurs.
Solution:
This PR addresses the issue by removing the parsing check from the createView method in Env. Instead, the check is moved to the respective classes responsible for creating views in the new and old optimizers.
