Looks like fastpath.c is passing a garbage isNull flag to the function
it calls :-(.  None of the functions "usually" called this way pay
attention to isNull, but plpgsql functions sure do.

Turns out I had already fixed this for 7.1 as a side-effect of some
other work, but I will stick a patch into 7.0.1.  If you're in a hurry,
the bug is in src/backend/tcop/fastpath.c, and the appropriate patch is

  #ifndef NO_FASTPATH
+     isNull = false;
      retval = fmgr_array_args(fid, nargs, arg, &isNull);
  #else
      retval = NULL;
  #endif     /* NO_FASTPATH */
