-------------------------------------------
Description: When we create a materialized view, the query specified in the
statement should be optimized by Calcite, as this might make a huge performance
difference when we materialize the results. (was: When we create a
materialized view, the query specified in the statement should be optimized by
Calcite, as this might make a huge performance difference when we materialize

Further, Calcite optimization should be trigger too when we execute {{ALTER
MATERIALIZED VIEW ... REBUILD}}, as the changes in the original tables might
lead to a new optimized plan.)
