Can not create service on postgres if default.json already has the connection string

https://stackoverflow.com/questions/44814788/how-to-create-feathersjs-services-with-knex-postgres/44815184#44815184

Steps to reproduce

While trying out FeathersJS, i tried to create two services following the docs. The first is called x and the other y.

When I create x with

~/r/feathers-chat ❯❯❯ feathers generate service
? What kind of service is it? KnexJS
? What is the name of the service? x
? Which path should the service be registered on? /x
? Which database are you connecting to? PostgreSQL
? What is the database connection string?
  postgres://user:password@localhost:5432/feathers_chat

Everything works perfectly.

When I create y

~/r/feathers-chat ❯❯❯ feathers generate service
? What kind of service is it? KnexJS
? What is the name of the service? y
? Which path should the service be registered on? /y
? Which database are you connecting to? PostgreSQL

The following error is thrown.

events.js:160
  throw er; // Unhandled 'error' event

It seems that the feathersJS client crashes when there a postgres connection defined in the default.js

So if i create the connection before hand, the client crashes upon creating the first service with the same exact error.

I uninstalled feathers-cli@2.2.2 and installed version 2.1.1 and I had no more problems.

System configuration

Module versions (especially the part that’s not working): feathers-cli@2.2.2 NodeJS version: v6.10.2 Operating System: MAC OS 10.12.4

Yes, it worked just fine in the previous version. l will give it a look

So it worked in a previous version? I think this regression might be caused by https://github.com/feathersjs/generator-feathers/pull/229
