- support alter MATERIALIZED VIEW mv1 replace with MATERIALIZED VIEW mv2 PROPERTIES('swap' = 'false');
- fix rename MATERIALIZED VIEW not change state of high level MATERIALIZED VIEW
Logic is the same as ALTER-TABLE-REPLACE. more detail pelase read doris document.
The difference is that this statement can only operate on materialized views
