I don't know, but Jonah's function can be better written using pure SQL,
which should be faster.  Something like this:

create table whatever (a text, b int);
insert into whatever
  select 'My text from iteration ' || a, a * 2
  from generate_series(1, 1000000) a;

I don't claim this works as is, but you should get the hang of it.
