title: Error when attempting knex seed:run after successful knex migrate:latest for remote database
body: <p>I'm running the following error when attempting to run <code>knex seed:run</code> against my remote postgres database (not localhost): <code>Knex:Error Pool2 - Error: connect ECONNREFUSED 127.0.0.1:5432</code>.</p>
  
  <p>I am able to run <code>knex migrate:latest</code> successfully and can see that the tables are created on my postgres server, but when I try to seed I get that error. I've run the same migrations/seed file against my local configuration and it has worked without a problem, but when I attempt to seed my heroku postgres instance, it throws this error (I'm not running my local pg service when I'm seeding the new db, which is likely why it's throwing an error).</p>
  
  <p>Any thoughts on why it is attempting to connect to localhost instead of the specified db? Sample of my file provided below:</p>
  
  <pre><code>var User = require("./models/User");
  var Project = require("./models/Project");
  
  exports.seed = function(knex, Promise) {
    console.log(knex.client.config.connection); //This returns the correct db info.
    return knex('user').del()
      .then(function() {
        return knex('project').del()
      }).then(function() {
        return new User({id: 1, firstName: "James", lastName: "Lee", phone: "123-456-2000", email: "test@test.com"}).save(null, {method: "insert"});
      }).then(function() {
        return new Project({id: 1, name: "Test"}).save(null, {method: "insert"});
      })
  };
  </code></pre>
