Believe me or not, but we have spent so much energy on this stuff that I
am ready to give up on the whitelist patch and focus on other business.
This doesn't change a couple of things though, so it is not *just* a
simple revert with the patch you mention applied:
- Adding a test for tablespaces makes sense.
- skipfile should be called after making sure that we work on a file.
- temporary files and temporary paths should be ignored.
- it is necessary to exclude EXEC_BACKEND files.
