Yep. It is not just limited to empty strings; An all blank string, no
matter the number of characters, is stored as NULL. And a corollary to
that idiocy is that a string with two blank characters is not equal to a
string with a single blank character in Oracle. 'a ' is not equal to 'a
'. 'a ' is not equal to 'a'. Port that to another database. Seen the
JOIN syntax? *sigh*
