I must have done this wrong. The actual error I get when I start from
scratch is this:

ERROR: make_date (bgroup): 0 args

That message comes from my program at the start of the function.

if (!CurrentTriggerData)
elog(ERROR, "make_date: triggers are not initialized");
if (TRIGGER_FIRED_FOR_STATEMENT(CurrentTriggerData->tg_event))
elog(ERROR, "make_date: can't process STATEMENT events");
if (TRIGGER_FIRED_AFTER(CurrentTriggerData->tg_event))
elog(ERROR, "make_date: must be fired before event");

if (TRIGGER_FIRED_BY_INSERT(CurrentTriggerData->tg_event))
rettuple = CurrentTriggerData->tg_trigtuple;
else if (TRIGGER_FIRED_BY_UPDATE(CurrentTriggerData->tg_event))
rettuple = CurrentTriggerData->tg_newtuple;
else
elog(ERROR, "make_date: can't process DELETE events");

rel = CurrentTriggerData->tg_relation;
relname = SPI_getrelname(rel);

trigger = CurrentTriggerData->tg_trigger;

nargs = trigger->tgnargs;
if (nargs != 4)
elog(ERROR, "make_date (%s): %d args", relname, nargs);

All I have before that is the declarations.
