I always break on errfinish myself.  At one time elog didn't go through
errstart (it may still not, I forget) so errfinish was the only
certainly common point for catching both elog and ereport.  Another
advantage is that by that point, all the error info is set up and you
can inspect it if you want to.

Also, control doesn't come to errfinish at all unless the message is
going to be printed, so the DEBUG-message problem goes away.
