Do you mean running a "make installcheck" with "force_parallel_mode=regress" in postgresql.conf? I did so with just CURSOR_OPT_PARALLEL_OK in PrepareQuery (like the original commit 57a6a72b) and still got 3 failed tests, all with CREATE TABLE .. AS EXECUTE .. . With my patch applied, all tests were successful.
