In addition to additional_base_classes, as recommended earlier, you can also just declare packages and subs after building the loader. Here is a trimmed-down example of my database.pl script, this is pre-loaded by mod_perl so that my website (which is HTML::Mason based) will have access to all the database objects it needs. In this snippet of code the classes JSK::Tag and JSK::Software are generated by Class::DBI::Loader from the tag and software tables in the database.

use Class::DBI::Loader;
use Data::Dumper;

my $loader = Class::DBI::Loader->new(
    dsn => 'DBI:Pg:dbname=jasonk',
    user => 'jasonk',
    password => 'yeah, right, I'll leave this in, sure',
    relationships => 1,
    options => { AutoCommit => 1 },
    additional_classes => [qw(Class::DBI::AbstractSearch)],
    additional_base_classes => [qw(JSK::DBUtils)],
);

# calling additional Class::DBI functions on the generated
# classes is easy
JSK::Tag->columns(Stringify => qw(tag));

# This package is for additional_base_classes, I don't
# have a table called 'dbutils', but all the generated
# Class::DBI tables inherit from this package.
package JSK::DBUtils;
use strict;
use warnings;
use Carp qw(croak);

sub some_cool_db_function { ... }

# The JSK::Software package is initially generated by
# Class::DBI::Loader to go with the 'software' table
# in the database, this just adds methods to that class
package JSK::Software;
use strict;
use warnings;

sub released {
    my $self = shift;
    return defined $self->release_date;
}
