Pass CURSOR_OPT_PARALLEL_OK to pg_plan_query() so that parallel plans are considered when running the underlying SELECT query. This wasn't done in commit e9baa5e9, which did this for CREATE MATERIALIZED VIEW, because it wasn't yet known to be safe. Since REFRESH always inserts into a freshly created table before later merging or swapping the data into place with separate operations, we can enable such plans here too.
