Attached, please find updated patch based on above lines. Due to addition
of projection path on top of partial paths, some small additional cost is
added for parallel paths. In one of the tests in select_parallel.sql the
plan was getting converted to serial plan from parallel plan due to this
cost, so I have changed it to make it more restrictive. Before changing, I
have debugged the test to confirm that it was due to this new projection
path cost. I have added two new tests as well to cover the new code added
I'm going to go work on this patch now.
Here is a revised version, which I plan to commit in a few hours
before the workday expires. I kept it basically as Amit had it, but I
whacked the comments around some and, more substantively, avoided
inserting and/or charging for a Result node when that's not necessary.
