TypeError [ERR_INVALID_CALLBACK]: Callback must be a function

On Node.js v9+ pg-db throws this error:

$ node
> db = require('pg-db')();
...
> db.query('SELECT NOW(), (err, rows) => console.log(err, rows) );
undefined

Looks like this is the bug in node-rand-token which was fixed in recent versions. Can you update the version of node-rand-token in package.json?

Thanks.

Are you on the latest version of this module?

The rand-token dependency was updated a few months ago (48f2401) and published to NPM as pg-db v2.0.0.

You're right, version 2.0.0 works fine. Sorry for the noise! Thanks!
