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?
