Hm. Line 2056 is this:

for (i = 0; i < ntriggers; i++)
{
Trigger *trigger = &trigdesc->triggers[tgindx[i]];

-> new_event->dte_item[i].dti_tgoid = trigger->tgoid;

It seems there must be something wrong with the trigdesc data structure
for that table, but what? Can you poke around in the corefile with gdb
print commands and determine what's wrong with the trigdesc?

Did that happen while this backend was running?
