Does this help at all ?

	(gdb) frame 2
	#2  0x00879bf7 in RI_FKey_cascade_del (fcinfo=0xbfbda9e4) at ./build/../src/backend/utils/adt/ri_triggers.c:917
	917     ./build/../src/backend/utils/adt/ri_triggers.c: Datei oder Verzeichnis nicht gefunden.
	(gdb) print trigdata
	$1 = (TriggerData *) 0xbfbdaca4

It is from another run, however.
