I noticed a small gap in our recent addition of default arguments for
functions in pg_proc.dat - it chokes if you try to set the default for a
VARIADIC "any" argument. But there's no need if the default argument us
NULL, as it often is. We don't need the argument's type_io_data etc. in
such a case. So this patch just handles NULL without fetching any type info.
