NAME

Hailo::Storage::PostgreSQL - A storage backend for Hailo using DBD::Pg

SYNOPSIS

First create a PostgreSQL database for failo:

    # Run it as a dedicated hailo user
    createdb -E UTF8 -O hailo hailo

    # Just create database..
    createdb -E UTF8 hailo

As a module:

    my $hailo = Hailo->new(
        storage_class => 'Pg',
        storage_args => {
            dbname   => 'hailo',
        },
    );
    $hailo->train("hailo.trn");

Or with complex connection options:

    my $hailo = Hailo->new(
        storage_class => 'Pg',
        storage_args => {
            dbname   => 'hailo',
            host     => 'localhost',
            port     => '5432',
            options  => '...',
            username => 'hailo',
            password => 'hailo'
        },
    );
    $hailo->train("hailo.trn");

From the command line:

    hailo --train hailo.trn \
        --storage      Pg \
        --storage-args dbname=hailo

Or with complex connection options:

    hailo --train hailo.trn \
        --storage      Pg \
        --storage-args dbname=hailo \
        --storage-args host=localhost \
        --storage-args port=5432 \
        --storage-args options=... \
        --storage-args username=hailo \
        --storage-args password=hailo

Almost all of these options can be omitted, see DBD::Pg's documentation for the default values.

See Hailo's documentation for other non-Pg specific options.
