Something along these lines perhaps:

CREATE TABLE
=# create table b( fk bigint references a(id), y text );
CREATE TABLE

  insert into b(fk, y) select ins_a.id, 'yy'||i.i from ins_a cross join
generate_series(1,10) as i(i);
INSERT 0 10
=# table a; table b;
id |   x
----+-------
1 | a row
(1 row)

1 | yy5

(10 rows)

Torsten,

You answered my question. The tables are already created and I'll need to
insert new rows table-by-table as I've done before now.

Thanks,

Rich
