Truncation of char, varchar types

Excessively long values are currently silently truncated when they are
inserted into char or varchar fields.  This makes the entire notion of
specifying a length limit for these types kind of useless, IMO.  Needless
to say, it's also not in compliance with SQL.

How do people feel about changing this to raise an error in this
situation?  Does anybody rely on silent truncation?  Should this be
user-settable, or can those people resort to using triggers?
