undefined socket if stop postgresql.service at beginning.

[szdailei]

Bug Report

lib/connection.js:

function onclose() {
  socket.removeListener('data', data)
  socket.removeListener('error', error)
  socket.removeListener('connect', ready)
  socket.removeListener('secureConnect', ready)
  closed = true
  close()
}

If I stop postgresql.service and then start program, socket will be undefined.

socket.removeListener('data', data);
^
TypeError: Cannot read property 'removeListener' of undefined
at Socket.onclose (file:///home/dailei/projects/www/packages/api-server/dist/index.js:1172:12)
at Object.onceWrapper (events.js:422:26)
at Socket.emit (events.js:315:20)
at TCP. (net.js:673:12)

I guess nodejs net.connect removes socket.
