I don't know --- I don't see it here.  I just ran your script as given,
and it worked.  (It produced zero rows of output, since the missing
nitems values meant that no data was loaded into the last few tables ...
but there was no backend crash.)

Is it crashing because of running out of memory, or something else?
Can you provide a backtrace?
