I am seeing it in the standalone backend here:

	debugtup (slot=0x856e0b0, self=0x84306d0) at printtup.c:548
	548                     printatt((unsigned) i + 1, typeinfo->attrs[i], value);
	(gdb) s
	printatt (attributeId=1, attributeP=0x856efa4, value=0x857201c "1", '0' <repeats 199 times>...) at printtup.c:480
	480             printf("\t%2d: %s%s%s%s\t(typeid = %u, len = %d, typmod = %d, byval = %c)\n",
