That probably means you're stomping on memory that doesn't belong to you. pallocs per se should not be a problem for COPY --- it does a context reset per row. And even if it didn't, you'd not likely be running out of memory after a mere thousand rows. However, a buffer-overrun type of coding error would be probabilistic as to when it became obvious via a core dump; some of the time you'd be stomping on memory that was unused anyway. regards, tom lane
