There's a reason why the database directory is not readable/writable
by unprivileged users: it's to prevent them from doing dumb things
like that. People who do have write access on the database are
assumed to know better.

Well, yes, but it would impose huge amounts of overhead in order to
raise an error a bit sooner for a stupid user action. The ideal
thing would be to prevent users from breaking their database in the
first place --- but there's not much we can do in that direction
beyond setting the directory permissions.
