COPY, like all the other utility commands in Postgres, doesn't support
$n parameters. (Basically, you can only use these where an expression
would be allowed, which is only in SELECT/INSERT/UPDATE/DELETE.)
You can work around this by constructing the desired command as a string
in plpgsql or one of the other PL languages, say
CREATE OR REPLACE FUNCTION public.update_dncl(bpchar, bpchar)
...
execute ''copy do_not_call_list (area_code, number) from '' || quote_literal($2) || ''
with delimiter ''
...
LANGUAGE 'plpgsql' VOLATILE;
