ERROR: permission denied for sequence cities_id_seq using Postgres

I\'m new at postgres (and at database info systems all in all). I ran following sql script on my database:

create table cities (
id serial primary key,
name          


        

Answer 1

Since PostgreSQL 8.2 you have to use:

GRANT USAGE, SELECT ON SEQUENCE cities_id_seq TO www;

GRANT USAGE - For sequences, this privilege allows the use of the currval and nextval functions.

Also as pointed out by @epic_fil in the comments you can grant permissions to all the sequences in the schema with:

GRANT USAGE, SELECT ON ALL SEQUENCES IN SCHEMA public TO www;
