Using COPY for that is not the best choice, as you see.
If you do it from psql, why not use \o?
test=> \pset tuples_only on
test=> \pset format unaligned
test=> \o func.sql
test=> SELECT pg_get_functiondef('first'::regproc);
test=> \q
$ cat func.sql
CREATE OR REPLACE FUNCTION laurenz.first(text, integer)
RETURNS integer
LANGUAGE sql
STABLE STRICT
AS $function$SELECT id FROM test WHERE val=$1 LIMIT $2$function$
Does that help?
Yours,
