Well, if we were to use SQL identifiers, we couldn't forbade anything
too much, seeing as almost anything can be used as an identifier, so
long as it is properly quoted.

But it seems to me like we could just pick an convenient subset which
doesn't make any OS too angry about it (say, reject / \ . and :), and
when we get to using actual SQL identifiers, we can enlarge the
supported char set without creating any backwards-compatibility problem.

On the other hand, this means the name has to be quoted if it would be
quoted as an SQL identifier, right?
