in reply to Perl, Pg, and Postgres
- You don't, or shouldn't directly. Check out Bruce's book on Creating Users. Or you can also view the CREATE USER syntax in the PostgreSQL Refference Manual.
- You should check CPAN for Pg and DBD::Pg. Personally I'd stick with DBI (DBD::Pg is a PostgreSQL driver for DBI) as it's a consistant API across many different databases.
- See above.
