NAME
    Class::DBI::Pg - Class::DBI extension for Postgres

      use strict;
      use base qw(Class::DBI::Pg);

      __PACKAGE__->set_db(Main => 'dbi:Pg:dbname=dbname', 'user', 'password');
      __PACKAGE__->set_up_table('film');

DESCRIPTION

     CREATE TABLE cd (
         id SERIAL NOT NULL PRIMARY KEY,

     __PACKAGE__->table('cd');
     __PACKAGE__->columns(Primary => 'id');
     __PACKAGE__->columns(All => qw(id title artist release_date));
     __PACKAGE__->sequence('cd_id_seq');
