I am wondering whether CREATE (with data) or REFRESH MATERIALIZED VIEW uses the parallel planner? When I EXPLAIN ANALYZE the query by itself (any query with parallel potential works here) without creating the materialized view, it shows that said query is parallel aware, and executing said query by itself shows multiple processors active using standard linux tools like top. Conversely, executing the query within a REFRESH or CREATE materialized view wrapper, does not show multiple processes, and using EXPLAIN on CREATE MATERIALIZED VIEW shows a query that is not parallel aware. Is this the intentional behavior and why? I was not able to find any information on this.
