dollar quoting can get you pretty far (bytea values can still be a problem):
create table foo(id int, a text, b text);
insert into foo values (1,'ab''cd', 'ab"cd');
create or replace function test_insert() returns void as
$$
declare
r text;
begin
select foo::text from foo limit 1 into r;
execute 'insert into foo select ($q$' || r || '$q$::foo).*';
end;
$$ language plpgsql;
