The function should work without an explicit close (or it would,
but for the security check). The file should appear on disk
immediately after the open, although the data might not be flushed
to disk until the file is actually closed, such as when the calling
session's postmaster exits (that's how a plperlu version behaves
on my test system, anyway). Not that I disagree with adding an
explicit close, but the example should still "work" without it.
