In your example you use an underscore as the first character. The way
you have done this it will probably exclude any other before row
triggers from firing, which may have altered the value of one or more
columns. The more probable choice for me would be to have a trigger that
came after all other before triggers, and so should have a different
name. It's just an example, so your choice is fine, but I think you
should bring out that point more clearly for the average developer.

Can we call the function "minimal_update_trigger", rather than min_...
