Waterline migrate existing database to waterline models without sails

I am trying to create a model for an existing database. I am NOT using sails. Just waterline stand-alone.I have the connection set to migrate safe. However, waterline is still trying to create a table that already exists in my pre-existing database. If I make the tableName a new name, it works fine. The problem seems to be when I try to use existing data in an existing table and then create a waterline model for it.

I believe this is a bug since migrate safe should never be trying to create a table at all right?

I am using waterline without sails.

Waterline is configured like this:

```
models = [];
fs.readdirSync(HOMEDIR + '/lib/models/waterline').forEach(function(file) {
  models.push(require(HOMEDIR + '/lib/models/waterline/' + file));
});

module.exports = {
  init: function(next) {
    models.forEach(function(model) {
      orm.loadCollection(model);
    });

    orm.initialize(config, function(err, models) {
      if (err) throw err;
      global.models = models.collections;
      global.connections = models.connections;
      next();
    });
  }
};


//And this in my config
localhost: {
      migrate: 'safe',
      adapter: 'postgres',
      database: 'intellinote',
      host: 'localhost',
      user: 'postgres',
      password: '',
      port: 5432
    }
``` 

using sails-postgresql by the way. "sails-postgresql": "^0.11.4",

One hypothesis I have is that my model definition does not match my postgresql model exactly. I have tried to do this but maybe I missed something small. Where in the waterline code does it check for model == schema definition? Maybe if I knew that, I could find why this is trying to do a create

Sails user for 3 years. Major production level bug at multi billion company :(

Thanks in advance

More info: The sql looks like this for the table

```
DROP TABLE IF EXISTS "intellinotedb"."external_resource";
CREATE TABLE "intellinotedb"."external_resource" (
    "id" int8 NOT NULL DEFAULT nextval('external_resource_id_seq'::regclass),
    "external_id" varchar(2000) NOT NULL COLLATE "default",
    "version_id" varchar(2000) COLLATE "default",

    "size" int8,

    "modified_at" timestamp(6) NULL,

    "note_id" int8,
    "type" varchar(50) NOT NULL COLLATE "default",
    "is_public" bool NOT NULL DEFAULT false,

)
WITH (OIDS=FALSE);
ALTER TABLE "intellinotedb"."external_resource" OWNER TO "intellinote";

-- ----------------------------

And my model:

    },
    creator: {

      required: true,
      size: 50
    },

    note_id: {

      size: 8
    },
    type: {
      type: 'string',
      defaultsTo: 'FILE',
      required: true,
      size: 50
    },

    },
    mime_type: {
      type: 'string',
      required: true
    },
    internal_type: {
      type: 'string',
      defaultsTo: 'REGULAR',
      required: true
    },
    is_template: {
      type: 'boolean',
      defaultsTo: false,
      required: false
    },
    has_filled_data: {
      type: 'boolean',
      defaultsTo: false,
      required: false
    }
  }
});
