Hm --- it is, or should be, always present in errors returned by the
backend.  I suspect this failure is occurring on the client side; libpq
does not produce broken-down fields in its error reports at the moment.
The weird limit suggests that the underlying problem is out-of-memory
while marshaling the query.
