In 8.0 you can use INSERT ... SELECT and generate_series():

http://www.postgresql.org/docs/8.0/static/sql-insert.html
http://www.postgresql.org/docs/8.0/static/functions-srf.html

Example:

INSERT INTO foo (serialnum) SELECT * FROM generate_series(1, 100);

Although older versions of PostgreSQL don't have generate_series(),
it's trivial to write with PL/pgSQL or other languages.  Read up
on set-returning functions or search the archives for examples.
