See comment in pgunlink() "We need to loop because even though
PostgreSQL uses flags that allow unlink while the file is open, other
applications might have the file
open without those flags.". Can you once see if there is any flag
that you have missed to pass to allow this? If there is nothing we
can do about it, then we might need to use some different API or maybe
define a new API that can handle this.
