You don't.  Unfortunately, SQL92 specifies the new behavior.

You might think about declaring the columns plain text and using
triggers to do the truncation, if you really want truncation to a
length limit.

Consider hacking pg_attribute.atttypmod or pg_attribute.atttypid, if the
reload time is too daunting.  (However, if you failed to reload your
data because of this error, it seems like you aren't in position to
avoid a reload anyway...)
