Currently, the explain analyze of parallel seq scan plan is not showing the allocated number of workers including the planned workers.I feel this information is good for users in understanding the performance difference that is coming with parallel seq scan. It may be missed in recent patch series. It was discussed in[1]. Currently there is no qualification evaluation at Result and Gather nodes, because of this reason, if any query that contains any parallel restricted functions is not chosen for parallel scan. Because of this reason, there is no difference between parallel restricted and parallel unsafe functions currently. Is it fine for first version?
