Ok, here someone was cheating by invoking a system library function
directly. That's no longer supported. If you really want this you need
to make a small library with PG_MODULE_MAGIC; and a pg_system() function
that redirects to the real system().
That said, why are you doint this anyway. A better solution may be to
install a trusted language (like plperlu or plpython) and do the system
call from there.

Here the column is defined as 12 characters and you're trying to
inserts a 19 character string, which is bad. How you got that out of
pg_dump though I don't know.
Have a nice day,
