It's just that ordinarily as the owner of an object, I can do what I
like with it. In this case, I can't. In fact, once I've created the
table I can't access it. I guess the surprising thing to me is that I'm
allowed to create it without usage privilege.

However, it is what it is, and as it is intended behaviour I will
happily work with it. Perhaps some extra notes in the documentation of
the sql-grants section might be useful.

As a side note: creating a file in a write-only directory on Unix
doesn't work for me.
