There is a great article about this exact problem: "getting multiple values from sequences".

If performance is not an issue, for instance when using the sequence values dwarfs the time used to get them or n is small, then the SELECT nextval('seq') FROM generate_series(1,n) approach is the simplest and most appropriate.

But when preparing data for bulk loads the last approach from the article of incrementing the sequence by n from within a lock is appropriate.
