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

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

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

DESCRIPTION
    Class::DBI::Pg automate the setup of Class::DBI columns and primary key
    for Postgres.

    select Postgres system catalog and find out all columns, primary key and
    SERIAL type column.

    create table.

     CREATE TABLE cd (
         id SERIAL NOT NULL PRIMARY KEY,
         title TEXT,
         artist TEXT,
         release_date DATE
     );

    setup your class.

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

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

    This is almost the same as the following way.

     package CD;

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

     __PACKAGE__->set_db(Main => 'dbi:Pg:dbname=db', 'user', 'password');
     __PACKAGE__->table('cd');
     __PACKAGE__->columns(Primary => 'id');
     __PACKAGE__->columns(All => qw(id title artist release_date));
     __PACKAGE__->sequence('cd_id_seq');

METHODS
  set_up_table TABLENAME HASHREF
    Declares the Class::DBI class specified by TABLENAME. HASHREF can
    specify options to when setting up the table.

    ColumnGroup
        You can specify the column group that you want your columns to be
        in.

           $class->set_up_table($table,  { ColumnGroup => 'Essential' });

        The default is 'All'
