Without above patch the make installcheck fails for select_into.sql with below diff
when force_parallel_mode = on max_parallel_degree = 3
To reduce the time of execution I can set the generate_series parameter to 500, which is fast in my machine and also fails with above diff but this time only one worker is assigned as per plan.
