Great, thanks!

I conciously omitted the "_dir" suffix - I'm not a great fan of long
function names, and we want to inspect the contents of archive_status
to find out about the status of the archiving process. But then, my
main concern is the functionality, not the name, we can easily change
the name. Is there any other opinion pro/contra the name?

I'm aware of that threat, and that Michael just commited "pg_ls_tmpdir()".
I'm not that sure about Laurenz' idea regarding monitoring all the
database directories (but it doesn't hurt anybody...). Anyway, the
archive_status directory is not coupled to any specific database or
tablespace, so there's not too much overlap.
