Prabhat and I have done some testing for this feature and written few
testcases. PFA the sql script(along with the expected .out files)

In addition we have generated the LCOV (code coverage) report and
compared the files which are changed for the "Parallel Bitmap Heap scan"
patch.
You can see the numbers for "with_patch" V/s "with_patch+TestCases"
(.pdf file is attached)
