Migrations in Postgres

[fiestacasey]

I'm trying to do a migration for postgres (new or existing table) and it doesn't seem to work. I can run queries fine, just no migration. Code follows:

conString = 'postgres://user:pass@localhost:5432/test'
jugglingdb = require('jugglingdb')
Schema = jugglingdb.Schema
pg_db = new Schema('postgres', { 'url': conString })

# Question model
Question = pg_db.define('Question', {
    text:   { type: String, length: 255 }
}, {table: 'questions'})
Question.validatesPresenceOf('text')

if !pg_db.isActual()
        console.log 'migrating datatables'
        pg_db.autoupdate (err) -> 
            if err?
                console.log 'error during migration '+err
            else
                console.log 'migration successful'

Log output
