TRIGGERED_DATA_CHANGE_VIOLATION is most certainly NOT an appropriate
code here --- it's talking about invalid database content states.
The RI triggers use ERRCODE_E_R_I_E_TRIGGER_PROTOCOL_VIOLATED for these
sorts of conditions, and I think that's probably best practice. See
ri_CheckTrigger() in particular.
