I'd like to check conditions by comparing actual values but not
a target of UPDATE statement because I think almost user expects
the former behavior. Unmodified UPDATE-targets are common case
if we use a framework that generates SQL statements internally.
Anyway, we need to compare the actual values if we want to treat
NEW value modifed by another trigger correctly.
