 One way to avoid this problem is to run
    <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
> on a machine where you can
    be sure that other processes will not run the machine out of
    memory.  If memory is tight, increasing the swap space of the
    operating system can help avoid the problem, because the
    out-of-memory (OOM) killer is invoked only when physical memory and
    swap space are exhausted.
